Make up a data set of at least 12 numbers that have the following landmarks maximum18 mode 7 range13 median 12?

I'll start you out.

With the max of 18 and range of 13, the highest score is 18 and the lowest is 18-13 = 5.

The most frequently occurring score is 7, and half the scores lie above 12 and half lie below.

I hope this helps.
