Frequently asked questions
How do I calculate the average?
Add the numbers and divide by how many there are. The average of 72, 85 and 90 is 247 ÷ 3 = 82.33.
What's the difference between mean and median?
The mean is the arithmetic average; the median is the middle value when sorted. They differ when the data is skewed.
How is a weighted average calculated?
Multiply each value by its weight, add them up and divide by the total weight.
