Description

Find Mean

Find the mean (average) of a list of numbers in an array.

Information

To find the mean (average) of a set of numbers add all of the numbers together and divide by the number of values in the list.

For an example list of 1, 3, 5, 7

1. Add all of the numbers

1+3+5+7 = 16

2. Divide by the number of values in the list. In this example there are 4 numbers in the list.

16/4 = 4

3. The mean (or average) of this list is 4

My Solution

def find_average(nums)
  nums.empty? ? 0 : nums.sum.to_f / nums.count
end
