• 84
• There is no median.

Find the First Quartile Q1 of the following numbers:

84, 88, 72, 74, 98, 16, 94

• 72

• 88

• 94

• There is no Lower Quartile.

Find the Third Quartile Q3 of the following numbers:

84, 88, 72, 74, 98, 16, 94

Find the IQR of the following numbers:
84, 88, 72, 74, 98, 16, 94 

• 78
• 22
• 16
• There is no IQR.

Use the 1.5 IQR rule to determine if there are any outliers for the following numbers:
84, 88, 72, 74, 98, 16, 94 

• Yes, 16 is an outlier.
• Yes, 33 is an outlier.
• Yes, 98 is an outlier.
• There are no numbers less than 39 or greater than 124, therefore there are no outliers.

Q1 = 53

Q2 = 55

Q3=61

• 73

• 40

• 80

• 73.5

Using the information below and the 1.5(IQR) rule, identify which of the following IS an outlier:

Q1 = 3

Q2 = 7

Q3 = 12

• 22

• 25.5

• -8.5

• 26

Find the outlier in the set of data
