How To Find The Mean?

To find the mean (average) of a data set:

1. Add up all the values in the data set.
2. Count the number of values in the data set.
3. Divide the total of the values by the number of values. This gives you the mean (average).

For example, if you have the data set: {2, 4, 6, 8},

1. Add up the values: 2 + 4 + 6 + 8 = 20
2. There are 4 values in the data set.
3. Divide the total by the number of values: 20 / 4 = 5

So the mean (average) of the data set {2, 4, 6, 8} is 5.
