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.
