Answer: 22
Step-by-step explanation: To find the average of this data set, remember that the average of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.
So to find the average of the data set shown here, let's begin by adding the numbers.
So we have 18 + 21 + 19 + 25 + 24 + 25.
This will be divided by how many numbers are in the set which is 6.
Adding the numbers, we get 132.
