You can put this solution on YOUR website! First, a frequency distribution is when a number is repeated one or more times. So, the list would be 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6, 6, 6, 7, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9, 9, 9, 10. That is your list of numbers to find the average of.
That is a total of 43 numbers totaling 239. The mean is 239/43 = 5.558
