Frequently asked questions
Sample or population standard deviation?
Use the sample version (divides by n − 1) when your numbers are a sample from a larger group, which is most of the time. Use the population version when you have every value.
What's the difference between mean and median?
The mean is the arithmetic average; the median is the middle value. The median is less affected by outliers, which is why it's used for things like home prices.
