how do you calculate mean

Thanks anon, that is a good description.

I would like to make one correction though :)

Median and mode are other measures of central tendencies but they are NOT other averages.

mean means the same as average.

You add up all the scores and then divide by how many there are :)

how do you calculate mean

Average is a synonym for arithmetic mean - which is the value obtained by dividing the sum of a set of quantities by the number of quantities in the set. An example is (3 + 4 + 5) ÷ 3 = 4. The average or mean is 4. Two other common forms of averages are the median and mode.
