Frequently asked questions

Should I use sample or population standard deviation?

Use sample (n−1) when your numbers are a subset of a larger population, which covers almost all real measurements. Use population (n) only when your data includes every member of the group.

When is the median better than the mean?

When the data is skewed or contains outliers. One extreme salary drags the mean upward but barely moves the median, which is why income is usually reported as a median.
