Question 7 of 18
Delicious77 [7]

The more appropriate measures of center and spread are:

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

<h3>Which measures are best for the given data?</h3>

The better measure of the middle would be the median because mean is affected by low and high values which are present in the given data set.

As mean is not being used, standard deviation should not be used for the same reason. This leaves us with the interquartile range which is best because it does not take outliers into account.
