What is an outlier in the data set 65, 32, 9, 76, 69?

Put the numbers in order

9,32,65,69,76

Q1 = (32 + 9) / 2 = 41/2 = 20.5

Q2 = 65

Q3 = (69 + 76) / 2 = 145/2 = 72.5

now we find the IQR which is Q3 - Q1 ... = 72.5 - 20.5 = 52

now we multiply 52 by 1.5 ... 52 * 1.5 = 78

so the outliers will be:

Q1 - 78 ... 20.5 - 78 = - 57.5 ... anything below this

Q3 + 78 ... 72.5 + 78 = 150.5 ... anything above this

there is no outliers in here
