Frequently Asked Questions

What is the difference between mean and median?
The mean is the sum divided by the count. The median is the middle value and is less affected by outliers.

When should I use the median instead of the mean?
Use the median when your data has outliers (extreme values), such as income data, which can be skewed by very high earners.

What is a weighted average?
A weighted average multiplies each value by a weight before averaging, giving more importance to some values than others.
