Jerry is a newly hired analyst to monitor the performance of Dunkin' Brands, an American restaurant holding company which runs two chains of fast-food restaurants: Dunkin' Donuts and Baskin-Robbins. Given the sales figures of all the stores across the United States, Jerry calculates the following statistics: Mean: the average of the sales figures. Median: the value separating the higher half from the lower half of the sales figures Mode: the number that occurs most frequently in the data Variance: it measures how far the sales figures are spread out from their average value Jerry recalls the implications of the statistics. Which one of them is correct?

sales figures are spread out from their
average value
Jerry recalls the implications of the
statistics. Which one of them is
correct?
Select one:
a. The median is not sensitive to
extremely low or extremely high
sales levels.
O b. There is no difference between
the mean and the median when
looking at the distribution of sales
data.
c. The variance is measured in the
same unit (dollars) as the sales
figures.
O d. For skewed distributions, the
mode is the best way of
summarizing the information.
