How could I find the mean of each set of numbers which is 21,25,27,32,36,37,43,43,44,51
How can I find the median of each set of numbers which is 26,71,33,69,71,25,75
And also how can I find the mode of each set of numbers 9,8,10,9,9,10,8

Mean = sum of scores/number of scores
Median = 50th percentile. Arrange scores in order of value. Middlemost score is median. If two middlemost scores, use their mean.
Mode is most frequently observed score.

okay thanks Jen, because the math questions I 've asked earlier, I don't really know what to do either add or divide the number to get the right number
