we have the data set

75,69,82,90,75,73,108,79,80

step 1

order from least to greater

69 73 75 75 79 80 82 90 108

Min=69

Max=108

Median=79

Q1=(73+75)/2=74

Q3=(82+90)/2=86

To find out the outliers

step 1

Find IQR -------> interquartile range

IQR=Q3-Q1

we have

Q3=86

Q1=74

IQR=86-74=12

Find out 1.5IQR -----> 1.5 times the interquartile range

1.5*(12)=18

so

Our fences will be 18 points below Q1 and 18 points above Q3

Lower fence=74-18=53

Upper fence=86+18=104

Any scores that are less than 53 and greater than 104 are outliers

In this case

108 is the outlier
