Statistical Analyses:

Descriptive Statistics:

Calculate mean, median, mode, standard deviation, and range for key numerical variables (e.g., Satisfaction Score, Age).

Summarize categorical variables (e.g., Gender, Loyalty Level, Purchase History) with frequency distributions and percentages.

Two-Sample t-Test (Independent t-test):

Compare the mean satisfaction scores between two independent groups (e.g., Group A vs. Group B) to determine if there is a significant difference in their average satisfaction scores.

Paired t-Test:

If there are two related measurements (e.g., satisfaction scores before and after a certain event), you can compare the means using a paired t-test.

One-Way ANOVA (Analysis of Variance):

Test if there are significant differences in mean satisfaction scores across more than two groups (e.g., comparing the mean satisfaction score across different Loyalty Levels).

Chi-Square Test for Independence:

Examine the relationship between two categorical variables (e.g., Gender vs. Purchase History or Loyalty Level vs. Support Contacted) to determine if there’s a significant association.

Mann-Whitney U Test:

For non-normally distributed data, use this test to compare satisfaction scores between two independent groups (e.g., Group A vs. Group B) to see if their distributions differ significantly.

Kruskal-Wallis Test:

Similar to ANOVA, but used for non-normally distributed data. This test can compare the median satisfaction scores across multiple groups (e.g., comparing satisfaction scores across Loyalty Levels or Satisfaction Factors).

Spearman’s Rank Correlation:

Test for a monotonic relationship between two ordinal or continuous variables (e.g., Age vs. Satisfaction Score or Satisfaction Score vs. Loyalty Level).

Regression Analysis:

Linear Regression: Model the relationship between a continuous dependent variable (e.g., Satisfaction Score) and independent variables (e.g., Age, Gender, Loyalty Level).

Logistic Regression: If analyzing binary outcomes (e.g., Purchase History or Support Contacted), you could model the probability of an outcome based on predictors.

Factor Analysis:

To identify underlying patterns or groups in customer behavior or satisfaction factors, you can apply Factor Analysis to reduce the dimensionality of the dataset and group similar variables.

Cluster Analysis:

Use K-Means Clustering or Hierarchical Clustering to group customers based on similarity in their satisfaction scores and other features (e.g., Loyalty Level, Purchase History).

Confidence Intervals:

Calculate confidence intervals for the mean of satisfaction scores or any other metric to estimate the range in which the true population mean might lie.

The average distance to surface diversion sources is expressed in kilometers. Today, cities are looking farther beyond their limits for clean water. On average, cities retrieve surface water from an average distance of 57.86 km.Note that if a city gets a small fraction of its water from surface water, there will be calculated values for this metric, but it is not particularly meaningful for a city's water risk or opportunity profile.For more information, access the Urban Water Blueprint report here: http://www.iwa-network.org/wp-content/uploads/2016/06/Urban-Water-Blueprint-Report.pdfYou can also visit the Urban Water Blueprint website here: http://water.nature.org/waterblueprint/#/intro=true

[Updated 28/01/25 to fix an issue in the ‘Lower’ values, which were not fully representing the range of uncertainty. ‘Median’ and ‘Higher’ values remain unchanged. The size of the change varies by grid cell and fixed period/global warming levels but the average difference between the 'lower' values before and after this update is 0.13°C.]What does the data show? This dataset shows the change in annual temperature for a range of global warming levels, including the recent past (2001-2020), compared to the 1981-2000 baseline period. Note, as the values in this dataset are averaged over a year they do not represent possible extreme conditions.The dataset uses projections of daily average air temperature from UKCP18 which are averaged to give values for the 1981-2000 baseline, the recent past (2001-2020) and global warming levels. The warming levels available are 1.5°C, 2.0°C, 2.5°C, 3.0°C and 4.0°C above the pre-industrial (1850-1900) period. The recent past value and global warming level values are stated as a change (in °C) relative to the 1981-2000 value. This enables users to compare annual average temperature trends for the different periods. In addition to the change values, values for the 1981-2000 baseline (corresponding to 0.51°C warming) and recent past (2001-2020, corresponding to 0.87°C warming) are also provided. This is summarised in the table below.

Instead of considering future climate change during specific time periods (e.g. decades) for this scenario, the dataset is calculated at various levels of global warming relative to the pre-industrial (1850-1900) period. The world has already warmed by around 1.1°C (between 1850–1900 and 2011–2020), whilst this dataset allows for the exploration of greater levels of warming. The global warming levels available in this dataset are 1.5°C, 2°C, 2.5°C, 3°C and 4°C. The data at each warming level was calculated using a 21 year period. These 21 year periods are calculated by taking 10 years either side of the first year at which the global warming level is reached. This time will be different for different model ensemble members. To calculate the value for the Annual Average Temperature Change, an average is taken across the 21 year period.We cannot provide a precise likelihood for particular emission scenarios being followed in the real world future. However, we do note that RCP8.5 corresponds to emissions considerably above those expected with current international policy agreements. The results are also expressed for several global warming levels because we do not yet know which level will be reached in the real climate as it will depend on future greenhouse emission choices and the sensitivity of the climate system, which is uncertain. Estimates based on the assumption of current international agreements on greenhouse gas emissions suggest a median warming level in the region of 2.4-2.8°C, but it could either be higher or lower than this level.What are the naming conventions and how do I explore the data?This data contains a field for the 1981-2000 baseline, 2001-2020 period and each warming level. They are named 'tas annual change' (change in air 'temperature at surface'), the warming level or historic time period, and 'upper' 'median' or 'lower' as per the description below. e.g. 'tas annual change 2.0 median' is the median value for the 2.0°C warming level. Decimal points are included in field aliases but not in field names, e.g. 'tas annual change 2.0 median' is named 'tas_annual_change_20_median'. To understand how to explore the data, refer to the New Users ESRI Storymap. Please note, if viewing in ArcGIS Map Viewer, the map will default to ‘tas annual change 2.0°C median’ values.What do the 'median', 'upper', and 'lower' values mean?Climate models are numerical representations of the climate system. To capture uncertainty in projections for the future, an ensemble, or group, of climate models are run. Each ensemble member has slightly different starting conditions or model set-ups. Considering all of the model outcomes gives users a range of plausible conditions which could occur in the future.For this dataset, the model projections consist of 12 separate ensemble members. To select which ensemble members to use, the Annual Average Temperature Change was calculated for each ensemble member and they were then ranked in order from lowest to highest for each location.The ‘lower’ fields are the second lowest ranked ensemble member. The ‘higher’ fields are the second highest ranked ensemble member. The ‘median’ field is the central value of the ensemble.This gives a median value, and a spread of the ensemble members indicating the range of possible outcomes in the projections. This spread of outputs can be used to infer the uncertainty in the projections. The larger the difference between the lower and higher fields, the greater the uncertainty.‘Lower’, ‘median’ and ‘upper’ are also given for the baseline period as these values also come from the model that was used to produce the projections. This allows a fair comparison between the model projections and recent past.

How to use the dataset

This dataset offers a detailed look at daily average, minimum, and maximum temperatures across the United States. It contains information from 1120 weather stations throughout the year to provide a comprehensive look at temperature trends for the year.

The data contains a variety of columns including station, station name, location (latitude and longitude), state name zip code and date. The primary focus of this dataset is on the AvgTemp, MaxTemp and MinTemp columns which provide daily average, maximum and minimum temperature records respectively in degrees Fahrenheit.

To use this dataset effectively it is useful to consider multiple views before undertaking any analysis or making conclusions:
- Plot each individual record versus time by creating a line graph with stations as labels on different lines indicating changes over time. Doing so can help identify outliers that may need further examination; much like viewing data on a scatterplot looking for confidence bands or examining variance between points that are otherwise hard to see when all points are plotted on one graph only.
- A comparison of states can be made through creating grouped bar charts where states are grouped together with Avg/Max/Min temperatures included within each chart - thereby showing any variance that may exist between states during a specific period about which it's possible to make observations about themselves (rather than comparing them). For example - you could observe if there was an abnormally high temperature increase in California during July compared with other US states since all measurements would be represented visually providing opportunity for insights quickly compared with having to manually calculate figures from raw data sets only.

With these two initial approaches there will also be further visualizations possible regarding correlations between particular geographical areas versus different climatic conditions or through population analysis such as correlating areas warmer/colder than median observances verses relative population densities etc.. providing additional opportunities for investigation particularly when combined with key metrics collected over multiple years versus one single year's results exclusively allowing wider inferences to be made depending upon what is being requested in terms of outcomes desired from those who may explore this data set further down the line beyond its original compilation starter point here today!

Research Ideas

• Using the Latitude and Longitude values, this dataset can be used to create a map of average temperatures across the USA. This would be useful for seeing which areas were consistently hotter or colder than others throughout the year.
• Using the AvgTemp and StateName columns, predictors could use regression modeling to predict what temperature an area will have in a given month based on it's average temperature.
• By using the Date column and plotting it alongside MaxTemp or MinTemp values, visualization methods such as timelines could be utilized to show how temperatures changed during different times of year across various states in the US

This table shows the average purchase price that has been paid in the reporting period for existing own homes purchased by a private individual. The average purchase price of existing own homes may differ from the price index of existing own homes. The average purchase price is no indicator for price developments of owner-occupied residential property. The average purchase price reflects the average price of dwellings sold in a particular period. The fact that de dwellings sold differs from one period to another is not taken into account. The following instance explains which problems are entailed by the continually changing of the quality of the dwellings sold. Suppose in February of a particular year mainly big houses with extensive gardens beautifully situated alongside canals are sold, whereas in March many small terraced houses are sold. In that case the average purchase price in February will be higher than in March but this does not mean that house prices are increased. See note 3 for a link to the article 'Why the average purchase price is not an indicator'.

Data available from: 1995

Status of the figures: The figures in this table are immediately definitive. The calculation of these figures is based on the number of notary transactions that are registered every month by the Dutch Land Registry Office (Kadaster). A revision of the figures is exceptional and occurs specifically if an error significantly exceeds the acceptable statistical margins. The average purchasing prices of existing owner-occupied sold homes can be calculated by Kadaster at a later date. These figures are usually the same as the publication on Statline, but in some periods they differ. Kadaster calculates the average purchasing prices based on the most recent data. These may have changed since the first publication. Statistics Netherlands uses figures from the first publication in accordance with the revision policy described above.

Changes as of 17 February 2025: Added average purchase prices of the municipalities for the year 2024.

When will new figures be published? New figures are published approximately one to three months after the period under review.

This dataset provides information about earnings of employees who are working in an area, who are on adult rates and whose pay for the survey pay-period was not affected by absence. Tables provided here include total gross weekly earnings, and full time weekly earnings with breakdowns by gender, and annual median, mean and lower quartile earnings by borough and UK region. These are provided both in nominal and real terms. Real earnings figures are on sheets labelled "real", are in 2016 prices, and calculated by applying ONS’s annual CPI index series for April to ASHE data. Annual Survey of Hours and Earnings (ASHE) is based on a sample of employee jobs taken from HM Revenue & Customs PAYE records. Information on earnings and hours is obtained in confidence from employers. ASHE does not cover the self-employed nor does it cover employees not paid during the reference period. The earnings information presented relates to gross pay before tax, National Insurance or other deductions, and excludes payments in kind. The confidence figure is the coefficient of variation (CV) of that estimate. The CV is the ratio of the standard error of an estimate to the estimate itself and is expressed as a percentage. The smaller the coefficient of variation the greater the accuracy of the estimate. The true value is likely to lie within +/- twice the CV. Results for 2003 and earlier exclude supplementary surveys. In 2006 there were a number of methodological changes made. For further details goto : http://www.nomisweb.co.uk/articles/341.aspx. The headline statistics for ASHE are based on the median rather than the mean. The median is the value below which 50 per cent of employees fall. It is ONS's preferred measure of average earnings as it is less affected by a relatively small number of very high earners and the skewed distribution of earnings. It therefore gives a better indication of typical pay than the mean. Survey data from a sample frame, use caution if using for performance measurement and trend analysis '#' These figures are suppressed as statistically unreliable. ! Estimate and confidence interval not available since the group sample size is zero or disclosive (0-2). Furthermore, data from Abstract of Regional Statistics, New Earnings Survey and ASHE have been combined to create long run historical series of full-time weekly earnings data for London and Great Britain, stretching back to 1965, and is broken down by sex.

Business Context

A research institute conducts a Talent Hunt Examination every year to hire people who can work on various research projects in the field of Mathematics and Computer Science. A2Z institute provides a preparatory program to help the aspirants prepare for the Talent Hunt Exam. The institute has a good record of helping many students clear the exam. Before the application for the next batch starts, the institute wants to attract more aspirants to their program. For this, the institute wants to assure the aspiring students of the quality of results obtained by students enrolled in their program in recent years.

However, one challenge in estimating an average score is that every year the exam’s difficulty level varies a little, and the distribution of scores also changes accordingly. The institute keeps a track of the final scores of its alumni who attempted the exam previously. A dataset constituted of a simple random sample of final scores of 600 aspirants from the last three years is prepared by the institute.

Objective

The institute wants to provide an estimate of the average score obtained by aspirants who enroll in their program. Keeping in mind the variation in scores every year, the institute wants to provide a more reliable estimate of the average score using a range of scores instead of a single estimate. It is known from previous records that the standard deviation of the scores is 10 and the cut-off score in the most recent year was 84.

A recent social media post from A2Z institute received feedback from a reputed critic, mentioning that the students from A2Z institute score less than last year's cut-off on average. The institute wants to test if the claim by the critic is valid.

Solution Approach

To provide a more reliable estimate of the average score using a range of scores instead of a single estimate, we will construct a 95% confidence interval for the mean score that an aspirant has scored after enrolling in the institute’s program. To test the validity of the critic's claim (the mean score of the students from A2Z institute is less than last year’s cut-off score of 84), we will perform a hypothesis test (taking alpha = 5%)

Data

The dataset provided (Talent_hunt.csv) contains the final scores of 600 aspirants enrolled in the institute’s program in the last three years.

How to use the dataset

This dataset provides a provider level summary of Inpatient Prospective Payment System (IPPS) discharges, average charges and average Medicare payments for the Top 100 Diagnosis-Related Groups (DRG). This data can be used to analyze cost and utilization trends across hospital DRGs.

To make the most use of this dataset, here are some steps to consider:

• Understand what each column means in the table: Each column provides different information from the DRG Definition to Hospital Referral Region Description and Average Medicare Payments.
• Analyze the data by looking for patterns amongst the relevant columns: Compare different aspects such as total discharges or average Medicare payments by hospital referral region or DRG Definition. This can help identify any potential trends amongst different categories within your analysis.
• Generate visualizations: Create charts, graphs, or maps that display your data in an easy-to-understand format using tools such as Microsoft Excel or Tableau. Such visuals may reveal more insights into patterns within your data than simply reading numerical values on a spreadsheet could provide alone.

Research Ideas

Medical Trial Case Study

1) Background Information

XYZ client is currently using Medication A for all their patients and is considering switching to Medication B. An essential aspect of evaluating Medication B is determining the anticipated usage in XYZ's patients. A trial was conducted to assess Medication B's effectiveness, and data for approximately 130 patients has been collected. This data includes information from at least 2 months prior to switching medications and up to 3 months after switching to Medication B.

Key considerations: - Patients can be on either Medication A or Medication B, but not both simultaneously. - Medication B is administered less frequently (~1 time per month) than Medication A. - The units for Medication A and Medication B are different and cannot be converted between each other. - Time on Medication A is defined as the period between the first and last recorded administration of Medication A. - A week is defined as 7 days, and a month is assumed to be 4.33 weeks.

2) Metadata of the File

The data file contains the following information:

**Admin: **
- ID: patient ID
- Med: Med type - Admin Date: Dates of administration - Units: Dosage units administered for each medication

Labs:
- ID: patient ID - DRAW_DATE: draw date - LAB_RESULT_CODE: different types of lab tests - LAB_VALUE: lab values

3) Business Goal

The main objective is to evaluate the potential adoption of Medication B by XYZ's patients. Specifically, the goal is to analyze the usage patterns, switching trends, and dosing behavior to make informed decisions regarding the transition from Medication A to Medication B. Additionally, the cost-effectiveness of Medication B compared to Medication A will be assessed.

4) Possible Questions and Analysis

1. Total Monthly Medication Usage: What is the total number of units administered for each medication in each month across all patients?

2. Patient Counts on Each Medication: How many patients received Medication A and Medication B from July to November?

3. Average Monthly Dose per Patient: What is the average total monthly dose per patient for each medication from July to November?

4. Switching Analysis: How many patients switched from Medication A to Medication B each month (September, October, November)? How many patients started on Medication B without being on Medication A in the past?

5. Time on Medication A Before Switch: For patients who switched to Medication B, what is the average number of weeks spent on Medication A before switching?

6. Dose Comparison Before and After Switch: What is the average monthly dose of Medication A for patients before switching to Medication B? What is the average monthly dose of Medication B post-switch? Breakeven Analysis: If Medication A costs $1 for 100 units, what is the breakeven price point for Medication B on a per-unit basis?

7. Dose Change Over Time: How does the average total monthly dose per patient (for both Medication A and B) change for patients switched in September vs. October vs. November?

8. Second Dose Analysis: For patients switched to Medication B: What percentage of the second Medication B dose is the same, higher, lower, or zero compared to the first dose? Lab Value Comparison: For patients that switched from Medication A to B, what was the average LAB B value while on Medication A compared to while on Medication B?

This structured approach will help identify the key metrics necessary to decide whether Medication B is a suitable replacement for Medication A across XYZ’s patients.

• Series: The name of the series, representing a specific category or topic.
• Sub-Series: Additional details or categorization within the series.
• Type: Specifies the type of activity being measured.
• Average Hours: The average number of hours spent on the activity.

These columns will be key in understanding and analyzing trends and patterns over time.

2. Focus on Series and Sub-Series

The 'Series' column represents specific categories or topics, while 'Sub-Series' provides additional details or categorization within those categories. Start by exploring these columns to gain an overview of different activities covered in this survey.

For example, you can filter by a particular series such as 'Work', then further narrow it down using sub-series like 'Paid Work' or 'Unpaid Work'. This will help you dive deeper into specific areas of interest.

3. Analyze Types of Activities

The 'Type' column specifies the type of activity being measured. It allows you to identify different types within each series/sub-series combination.

Use this information to segment activities based on their nature or characteristics. For instance, within the Leisure series, you may have sub-series like Socializing, Sports, and Entertainment. Analyzing these types individually can provide unique insights into how people spend their leisure time over a decade.

4. Investigate Average Hours Spent

The 'Average Hours' column quantifies how much time individuals spent on each specified activity on average. Use this numerical data to identify activities that are more time-consuming compared to others.

As you explore different series, sub-series, and types of activities, pay attention to any significant changes in the average hours spent over the years. This will allow you to uncover interesting trends and patterns in time use over the decade covered by this dataset.

5. Combine Filters for Deeper Analysis

To perform more specific analysis, combine multiple filters from different columns simultaneously. For example, you can filter by a particular series like 'Leisure' and then choose a specific sub-series like 'Sports'. Next, further narrow down your analysis by selecting a

Exploring County-Level Correlations in Cancer Rates and Trends

A Multivariate Ordinary Least Squares Regression Model

By Noah Rippner [source]

About this dataset

This dataset offers a unique opportunity to examine the pattern and trends of county-level cancer rates in the United States at the individual county level. Using data from cancer.gov and the US Census American Community Survey, this dataset allows us to gain insight into how age-adjusted death rate, average deaths per year, and recent trends vary between counties – along with other key metrics like average annual counts, met objectives of 45.5?, recent trends (2) in death rates, etc., captured within our deep multi-dimensional dataset. We are able to build linear regression models based on our data to determine correlations between variables that can help us better understand cancers prevalence levels across different counties over time - making it easier to target health initiatives and resources accurately when necessary or desired
