Some of the teachers at Ellison Park Elementary measured their active heart rates

after running in place for 3 minutes. Here are their results:

120, 135, 150, 125, 133, 114, 155, 160, 128, 140, 150, 130, 142, 145, 154

Create a box plot of their data.



Now list and then label the following on your box plot.

? Median

? First quartile (Q1)

? Third quartile (Q3)

? Upper extreme (max)

? Lower extreme (min)

What is the interquartile range of the data?
