Question

4. The ages of the members of a volunteer group are shown below: 13, 14, 14, 14, 15, 15, 15, 16, 16, 21, 23 Which box plot best represents this data? F 13 15 17 19 21 23 13 15 17 21 23 H < 15 19 15 17 19 21

Answer 1

First, we need to calculate the median

13, 14, 14, 14, 15, 15, 15, 16, 16, 21, 23

we have 11 values the media is the 6th value in this case 15.

the lower extreme is 13 the upper extreme is 23.

The lower quartile is 14 and upper quartile is 16

the box plot is
