A Statistics teacher has the following test scores : 93, 72, 80, 95, 90, 70, 91, 85, 86, 100 What is the median test score of these grades ?
The median means the number in the middle. Put the numbers in order from least to greatest and then cross them out at each end one by one until you get to the one in the middle. If there are two left, take the average of them. Post your answer here if you want it checked.
i HAVE AN ANSWER OF 90
I see two scores in the middle -- 86 and 90.
Follow Jen's directions for determining the median.
