How do I calculate the average of a set of numbers?
assistant
To calculate the average of a set of numbers, you need to add all the numbers together and divide the total by the number of numbers in the set. For example, if you had the numbers 1, 3, 5, and 7, then you would add 1 + 3 + 5 + 7 to get 16. Then divide 16 by 4, since there are 4 numbers in the set, to get 4 as the average.
