YOUR SMALL STATISTICS LAB
From numbers
to a clear answer.
Paste a dataset. Understand the distribution. Take the results into your next project.
Frequencies for integer values 2 to 9, from left to right.
FOCUSED TOOLS FOR REAL WORK
Where shall we start?
One consistent workspace.
Eleven different questions.
Standard deviation
How far do your values spread around their mean?
Open calculator ↗Variance
Measure spread in squared units.
Open calculator ↗Mean, median and mode
Three different ways to locate the centre of your data.
Open calculator ↗Quartiles and IQR
Explore the middle 50% and flag extreme observations.
Open calculator ↗Percentiles
Find any percentile from 0 to 100 with a stated method.
Open calculator ↗Z-score from a dataset
Compare a value to the mean of your dataset.
Open calculator ↗Weighted mean
Non-negative relative weights. No weighted variance or uncertainty estimate is calculated.
Open calculator ↗Pearson correlation
Linear association is not causation. Check the scatter plot. No p-values, confidence intervals or significance claims are produced.
Open calculator ↗Simple linear regression
Ordinary least squares with a fitted intercept. RMSE uses n; residual standard error uses n − 2 and needs at least 3 pairs.
Open calculator ↗Mean confidence interval
Estimate the mean and its uncertainty margin using the t distribution.
Open calculator ↗Spearman rank correlation
Compare the ordering of two series, including ties and a Pearson comparison.
Open calculator ↗Paste or import
Excel data, text or CSV. Choose your separators and column without hidden conversions.

Sample or population, formulas and quantile conventions are explicitly stated.
