All statistical measures are calculated instantly: mean, median, mode, standard deviation, variance, quartiles, and more.
3

Explore the histogram

A histogram shows the distribution of your data. Outliers are highlighted.

What is the difference between population and sample standard deviation?

Population standard deviation divides by N, sample divides by N-1. Use sample when your data is a subset of a larger population.

How are outliers detected?

Using the IQR method: any value below Q1 - 1.5 x IQR or above Q3 + 1.5 x IQR is flagged.

Can I paste data from a spreadsheet?

Yes. Copy a column from Excel or Google Sheets and paste it directly.

Is my data sent to a server?

No. All calculations run entirely in your browser.

Paste or type a set of numbers and instantly see every key statistical

measure: mean (arithmetic, geometric, harmonic), median, mode, range,

standard deviation and variance (both population and sample), quartiles,

interquartile range, skewness, and kurtosis. An auto-binned histogram

visualises your data distribution. Outliers are flagged using the IQR

method. Export all results as text. All processing runs in your browser.

Calculate percentages instantly — find X% of Y, what percentage X is of Y, or the percentage change between two values.
