The scores of several classmates on a math test are shown below: 91 points 77 points 90 points 79 points 81 points 85 points 86 points 76 points 75 points 80 points what is the median score for these students? 80 points 80.5 points 81 points 81.5 points

First we put them in order
75,76,77,79,80,81,85,86,90,91

the median is the middle number...however, in cases where there are an even number of numbers, ur gonna have 2 middle numbersso u take the average of those 2 numbers...basically, u add them and divide by 2.
So we have 2 numbers in the middlewe add them and divide by 2 to get the median.
(80 + 81) / 2 = 161/2 = 80.5 <== the median
