Step 1

The mean of the data is calculated as follows:

Step 2

Median is the middle most items. There are 21 items. Therefore, median is the 11th ((21+1)/2) item in the ordered arrangement (ascending or descending) of the data values.

The data in ascending order is as follows:

0,0,0,0,0,1,1,1,1,1,2,2,2,3,3,4,4,4,4,4,5.

Therefore, median is 2 (11th item in the ordered arrangement).

The sum of squared deviations is calculated as follows:

Step 3

The sample variance is calculated...
