Question

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: the standard deviation b. better measure of spread: the interquartile range (iqr) c. better measure of center: the median d. better measure of center: the mean

Explanation:

The data appears skewed (tail on the right side). For skewed - shaped data, the median is a better measure of the center as it is not affected by extreme values. The inter - quartile range (IQR) is a better measure of spread for skewed data as it is also resistant to extreme values, while the standard deviation is sensitive to extreme values.

Answer:

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