Here is a chart show how many shirts a man sold in 10 weeks.

Now what I want you to do is find the Mean, Median, Mode, and Range
The first thing I'll do is rearrange the set of data.
7,7,7,8,9,9,10,11,12,50. Mean 13 Median 9 Mode 7 Range 43
The best measure of central tendency, in this case, is the median (9) since many numbers in the set of data are close to it.
How many shirts should the man buy for the next 30 weeks?
Since nine is the best representative, I will multiply 9 by 30.
9x30=270
The man should buy 270 shirts.
Here are some things I found to help you understand measures of central tendency more:
This one I actually made,
