Section I: Multiple Choice Choose the best answer for each question.
Based on the shape of this distribution, what measures of center and spread would be most appropriate to report?
(a) The mean and standard deviation
(b) The mean and the interquartile range
(c) The median and the standard deviation
(d) The median and the interquartile range
(e) The mean and the range
ANSWER:Step 1 of 2
The median and interquartile range should be used as measures of center and spread.
Median and interquartile range are unbiased estimators of center and spread and since the data is so heavily skewed right, mean and standard deviation become unreliable.
