StatsLab is an interactive statistics playground. Explore datasets, compute descriptive stats, visualize distributions, and run inferential tests — all in one place.
Built for students, educators, and anyone who wants to understand data without wrestling with spreadsheets.
Jump in with built-in datasets from education, health, business, biology, and the environment — or paste your own numbers.
Instantly compute mean, median, mode, standard deviation, variance, quartiles, skewness, and kurtosis.
Render histograms, line charts, and normal curves to see the shape of your data at a glance.
Run one-sample t-tests and correlation analysis without switching tools or writing formulas.
Every result is paired with plain-language context so you can understand what the numbers actually mean.
StatsLab walks you through the entire analysis pipeline: pick a dataset, view summary statistics, visualize the distribution, and test hypotheses — no code required.
