To calculate the mean of a data set, you first add up all the values, then divide the total sum by the number of values. The document provides an example of finding the mean of the data set {48,46,44,35,32} by adding the values to get 205, then dividing by 5 values to get the mean of 41. It also lists two activity problems asking students to find the mean of other data sets.

1. Mean To find the mean, first find the sum of the numbers. Then divide by the number of addends.

2. Find the mean of 48,46,44,35, and 32 Step 1 Add all the numbers 48 46 + 44 35 32 205 Step 2 Divide the sum by the number of addends. 41 5 205 Step 3 The mean is 41
