Mean (average of all data points)
The mean is effectively the average value in a data set.
To find the mean, add up all your values, then divide by the number of values.
For instance,
Given the data set: 2, 3, 5, 6, 5
Total of values: 21
There are 5 values in the set, so the mean is 21 รท 5 which is 4.2
