What can this tool do?
Paste any set of numbers (separated by spaces, commas, newlines or CSV) to get count, sum, mean, median, mode, range, variance, standard deviation, min/max and the lower/upper quartiles, plus a histogram of the distribution. Switch between population and sample standard deviation. Useful for homework, grade analysis or a quick sense of how concentrated and spread your data is. Everything runs locally.
FAQ
Population vs sample standard deviation?
Sample SD divides by n−1 and estimates the spread of a wider population (most common); population SD divides by n and describes a fully known set. Use the checkbox to switch.
What if there are multiple modes?
All values tied for the highest frequency are listed, separated by commas; if every value appears once, it shows "no mode".
