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. Middle-most score is median. If two middle-most 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
