Best ResponseYou've already chosen the best response.2you should find the median of each data set divide the data set into two halves: one below and one above the median then find the median of each half IQR= top median  bottom median

Best ResponseYou've already chosen the best response.2because the numbers are sorted, and you have 10 numbers total, look at the middle number of the first 5 (i.e the 3rd number on the list) and the middle number of the lower 5 (i.e. the 3rd from the bottom) subtract those two numbers

Best ResponseYou've already chosen the best response.2in other words, if you look only at 100 100 100 95 95 (the first 5 numbers of the midterm) the median of those is the middle number and is 100

Best ResponseYou've already chosen the best response.2now do the same thing for the bottom 5 numbers 92 92 88 85 75

Best ResponseYou've already chosen the best response.2you should get 88 for the median of the bottom 5 numbers. now you can find the IQR 100  88
