Make up set of 7 numbers having these landmarks: mode 21, Median 24, maximum 35, range 20.
If the maximum is 35 and the range is 20, that means the minimum is 15.
15 __ __ __ __ __ 35
We know the median (number in the middle) is 24.
15 __ __ 24 __ __ 35
The mode (used most often) is 21. We have to have two 21's, because it has to be used more than the others, and we can't have more than 2 because there is no room.
15 21 21 24 __ __ 35
Now that we fit all the conditions, the remaining two spots can be any numbers between 24 and 35 as long as we don't repeat numbers (because then 21 wouldn't be the mode).
15 21 21 24 25 31 35
