Sorry

This answer is incorrect.

To find the average of any set of data all that needs to be done is to add up all the data and divide by the total number of data items.

In this case:

5.2 + 5.6 + 4.5 + 5.0 + 5.2 = 25.5

Then divide 25.5 by the number of data items, in this case 5

25.5 divided by 5 = 5.1

Now let us try another one
