To find the interquartile range, you would list the data that comes from the stem and leaf plot:

10, 23, 23, 28, 33, | 45, 56, 67, 80, 90; | marks where the median would be.

The 2 numbers underlined represent he 1st(lower) and 3rd(upper) quartiles.  Subtract these to find the interquartile range.

67 - 23 = 44

44 is the IQR.
