Answer:
quartile 1 is 39
quartile 2 is 69.5
quartile 3 is 78
the minimum is 37
the maximum is 82
IQR is 39
Explanation:
you organize the data so that it’s from least to greatest. quartile 2 would be 69.5 because 67 and 72 were both in the middle. When that happens, you add them both and divide by 2. For the other quartiles you find the middle number of both sections :)
the IQR is just (quartile 3 - quartile 1)
I hope this helped :)
