The arithmetic mean is defined as the sum of the individual members of the population divided by the number of members. The mean score for the nine members of Mt. Dexter's team is (15 + 20 + 19 + 20 + 16 + 20 + 14 + 18 + 17) / 9 = 159/9 = 17 and 2/3 (17.666 repeating)

What is the trick for calculating mean. I mean some decent trick to make me do it in my head?
You add the scores together and then divide by the number of scores. So if you rolled a dice and your scores were, 3, 5, 2, and 6 You would add these together, getting 16, and then you would divide this by 4 (because you have 4 scores) and so your mean would be 4 (16/4=4) sum of scores / number of scores = mean. Hope this helps.
