A (hopefully) Easy Question about the Interquartile Range

Construct a box-and-whisker plot for the data with a minimum of 34, first quartile of 37, median of 42, third quartile of 52, and a maximum of 60. Solve for the interquartile range. Upload your plot for your teacher to review.

Ok, so I know how to construct a box-and-whisker plot, I just want to make sure that I have solved for the interquartile range correctly.

This is the formula for interquartile range:
IQR= xu-xl

I am thinking, from the data, that the upper quartile would be 60 and the lower quartile would be 34. Am I correct in assuming that the minimum is the lower quartile and the maximum is the upper quartile? I guess that is my main question here.

So, I have done:

IQR=60-34

IQR=26

Did I do this correctly? Thanks!
