Median is the middle number. Rearrange the numbers to smallest to biggest. 70, 77, 80, _, 82, 87, 88 If the median of the data set is 81 the middle number needs to be 81. So the missing number is 81. 70, 77, 80, 81, 82, 87, 88
It is 81 because well first you order the numbers from lowest to greatest then start crossing a number off from each side of the numbers until you get a equal amount crossed in each side there will be one number left that’s not crossed off and it will be 81
