Question

For the following set of 20 numbers:

1, 3, 20, 23, 25, 30, 30, 31, 32, 33, 33, 34, 34, 40, 40, 42, 43, 43, 44, 44

Are there any outliers in the data set above? Use the 1.5 IQR rule to check.

Q1 =



Q3 =



IQR =



IQR(1.5) =



Q3 + IQR(1.5) =
(Upper outlier)


Q1 - IQR(1.5) =
(Lower outlier)

Answer 1

I cannot answer all of this, so I will only answer what I can:

Q1: 13

Q3: 22.5

IQR: 13.5

IQR(1.5): 20.25

Q3 + IQR(1.5) = 43

Q1 - IQR(1.5) = -7.25

I don't know if my calculations are all right but I hope this helps! :)
