Explanation:

1. Number of absent students:

0,1,1,0,3,2,5,1,9,0

Find the:

Mean

0, 0, 0, 1, 1, 1, 2, 3, 5, 9/10

= 22/10

= 2.2

Median

0, 0, 0, 1), 1, 1, (2, 3, 5, 9

= 1 + 1/2

= 2/2

= 1

Lower quartile

Upper quartile

Range

= 9 - 0

= 9

Interquartile range = 3

Mean absolute deviation = 2.08

Standard deviation = 2.71
