question 5 of 25
what are the more appropriate measures of center and spread for this data set?
select two choices: one for the center and one for the spread.
a. better measure of spread: standard deviation
b. better measure of center: mean
c. better measure of center: median
d. better measure of spread: interquartile range (iqr)

Explanation:

Step1: Analyze data distribution

The data appears skewed.

Step2: Recall measure - center rules

For skewed data, median is a better measure of center as it is not affected by outliers.

Step3: Recall measure - spread rules

For skewed data, inter - quartile range (IQR) is a better measure of spread as it is also robust to outliers.

Answer:

C. Better measure of center: median
D. Better measure of spread: interquartile range (IQR)
