1. ## Five Number Summary

Dataset: 34, 37, 40, 43, 46, 49, 50, 53, 55, 59, 60, 61, 61, 63, 64, 67, 71, 71, 72, 76

n = 20

Min = 34
Q1 = 46
Median = 59.5
Q3 = 67
Max = 76

This is all right, isn't it?

---------------------------------------------------------------------------------------------------

Dataset: 0, 1, 2, 3, 3, 3, 3, 4, 4, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 11, 12

Median = 5
Q1 = 3.5
Q3 = 7
IQR = 3.5
Upper Boundary = 29.75
Lower Boundary = 7

I don't think that the boundaries are right, as they make 12 results outliers.

Please show me how to work these out.

What is the definition of the quartiles you have been given? For example a common definition for Q1 and Q3 in this case would put these at 47.5 and 65.5.

Quartiles and median are wrong.

Thanks.
