Answer:
Explanation:
so the mean is the average which you can get by adding all the scores together and then dividing them by the number of scores
2+13+14+15+15+16+16+16+17+17+17+17+17+18+18+18+18+19+19+20+20=342
342/21=16. 2857(and on and on) which we can round to 16 or 16.3 or 16.29 (depends on how you are told to round.
The median is the middle which is 17
the mode is the number that has the most which is also 17
the range is 18 ( 20-2= 18)
the outlier is the digit that is very different than the others in this case 2
