UPSC CSAT Statistics — Distributions & Data Sets
UPSC CSAT Paper II tests quantitative aptitude including descriptive statistics, probability, and data interpretation under strict time constraints. This simulator presents curated data sets — population tables, survey results, and frequency distributions — and asks you to compute summary statistics, identify distribution shape, and answer MCQs at CSAT difficulty level. Building fluency with mean-median-mode relationships and normal distribution properties is key to scoring in this section.
What you can do in this simulation
- Load a sample data set and compute mean, median, mode, and standard deviation interactively
- Identify skewness from histogram shape and relate it to mean-median-mode ordering
- Plot a frequency distribution and fit a normal curve to read off probability intervals
- Solve timed CSAT-style data interpretation passages with tables and bar charts
- Compare performance across practice attempts and identify weak concept areas
Concepts covered
mean · median · mode · standard deviation · normal distribution · data interpretation
