Question

Use the data set to find the quartiles and the minimum and maximum data elements.

82, 37, 39, 66, 72, 78, 67, 82
Quartile 1 =

Quartile 2 =

Quartile 3 =

IQR =

Minimum =

Maximum =

Answer 1

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 :)
