Answer: 9; 21; The mean reflects the center more while the median reflects the more common numbers without the outlier (42).
Explanation:
The median is the middle number when all of the numbers are arranged from least to greatest.
8, 8, 9, 9, 9, 9, 9, 10, 10, 40
In this case, there are two nines in the middle. So, the median is 9.
The mean is the same as the average. So, you add all of the numbers together and divide that by the amount of numbers.
(8+8+9+9+9+9+9+10+10+40)/10
121/10
In this problem, the mean (average) is 12.1.
For this problem, the mean reflects the center more while the median reflects the more common numbers without the outlier (42).
