Question

The interquartile range of a data set is 10 units. What does this represent?

A) There are 10 units below the lower quartile.
B) The median value of the data set must be 10 units.
C) There are 10 units between the upper and lower quartiles.
D) The middle 50% of the data in the set are less than 10 units.

Answer 1

Answer:

the interquartile range is the range between the two quartiles in the data.

these are the upper and lower quartiles.

if the interquartile range is 10, then 10 is also the value of the difference between the upper and lower quartile.

since their difference is 10, there must be a value of 10 units between the upper and lower quartiles.
