Question

Which box-and-whisker plot is the correct drawing for the following data? 38, 29, 23, 23, 34, 25, 36, 35, 20, 17, 24, 25, 27, 20, 30

Answer 1

Explanation:

38, 29, 23, 23, 34, 25, 36, 35, 20, 17, 24, 25, 27, 20, 30

17 20 20 23 23 24 25 25 27 29 30 34 35 36 38

Number of values = 15

Median = 8th value = 25

First quartile

First quartile would be the half of the median i.e., the 4th value

First quartile = 23

Third quartile

Third quartile would be the half of the median. Start counting from the 9th value.

Third quartile = 34

One whisker would start at 17 and the other would be at 38.
