Step-by-step explanation:
To find the mean of a set of numbers, we need to add up all the values and then divide the sum by the total number of values.
Given set: 25, 14, 16, 25, 30
Step 1: Add up all the values.
25 + 14 + 16 + 25 + 30 = 110
Step 2: Count the total number of values.
There are 5 values in the set.
Step 3: Divide the sum by the total number of values to get the mean.
Mean = 110 / 5 = 22
Therefore, the mean of the set 25, 14, 16, 25, 30 is 22.
