What is the interquartile range of the box-and-whisker plot shown?


54
45
43
34

Answer 1

do you see the end lines that make up the box of the box and whisker plot?

Answer 2

YES

Answer 3

so that length is the interquartile range. the lower line (left) of the box is at the 1st quartile. the middle line (in the box) is the 2nd quartile, also known as the median. and the last line (right) of the box is at the 3rd quartile.
the interquartile range is calculated by subtracting the 1st quartile from the 3rd quartile.

does that help?
