Frequently asked questions

How is the average calculated?

Add all the numbers and divide by how many there are. For 72, 85 and 90 the mean is 247 ÷ 3 = 82.33.

What is the median?

The middle value after sorting. With an even count it is the average of the two middle values.

What if there is no mode?

If no value repeats more often than the others, there is no mode. If several values tie for most frequent, all of them are shown.

When should I use a weighted average?

When some values count more than others, like subject marks with different credits, or prices bought in different quantities.

Which standard deviation is shown?

The main value is the population standard deviation; the sample standard deviation (dividing by n − 1) is shown under it.
