Statistics Calculator
Paste numbers one per line or separated by commas to get the mean, standard deviations and quartiles at once. Add y values for regression and correlation.
How to use
- Put your data in the x column. A column copied from a spreadsheet pastes straight in.
- If values repeat, turn on Frequency and enter how many times each occurs.
- For paired data, turn on y and pick a regression model. Below the results you can estimate ŷ from x or x̂ from y.
- Quartiles use the school scientific calculator method by default. Switch the method to match Excel’s QUARTILE.INC.
σ (population SD) is the square root of the mean squared deviation; s (sample SD) divides by n − 1 instead. See population vs sample standard deviation for which one to use.
