Step-by-step explanation:

54/(how many numbers there are, which is 6)=9.

Your mean value is 9.

The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

So, start by adding the numbers to get 54.

54 will be divided by the number of numbers in the set, or 6.

54 divided by 6 is 9.

So the mean of this data set is 9.
