Determine the Appropriate Measure of Center and Variability

Which measurements would represent the BEST measures of center & variability for the data set shown?

• Mean

• Median

• IQR

• Range

For this data set, the​ (a)   is the best measure of center and the​ (b)   is the better measure of variation.

• median

• IQR

• range

• mean

• mode

What is the median ticket price?

• $8

• $5

• $33

• $35

Find the IQR of the distribution.

(only type in the number)

(a)  

Given the data: 21, 31, 26, 24, 28, 26
This is a 3 part question:
Part-1: What is the mean of the data?

• 24

• 25

• 26

• 27

What is the median of the data?

• 105

• 106

• 104

• 110

Which statement is true?

• Set A has the lesser range

• Set B has the greater median

• Set A has the greater mean

• Set B is less symmetric than Set A

Study the graph and determine one measure of center and one measure of variability that would best describe the data. (hint: are there outliers?)

• Range

• Median

• Mean

• IQR

Select the (2) measures of CENTER.

• Mean

• Median
