Professional athletes’ salaries.The salaries of superstar professional athletes receive much attention in the media. The multimillion-dollar long-term contract is now commonplace among this elite group. Nevertheless, rarely does a season pass without negotiations between one or more of the players’ associations and team owners for additional salary and fringe benefits for allplayers in their particular sports.

a.If a players’ association wanted to support its argument for higher “average” salaries, which measure of central tendency do you think it should use? Why?

b.To refute the argument, which measure of central tendency should the owners apply to the players’ salaries? Why?

Short Answer

Expert verified
  1. Median
  2. Mean

Step by step solution

01

Identifying the best measure of central tendency to support the argument

Suppose the players’ association wants to support its argument for a higher average salary. They should use the median because the median gives you the centermost value and would therefore give us the appropriate average.

Lower median as the average will prompt the owners to increase the median and thus increase the average.

02

Finding the best measure of central tendency to refute the argument 

The owners will use the mean because there are very high chances that the data might be skewed to the right and would pull the mean to the right and make it larger than the median value.

By using the mean in skewed data, the owners can refute the argument by showing the already higher average.

Most popular questions from this chapter

Discuss the conditions under which the median is preferred to the mean as a measure of central tendency.

Explain why we generally prefer the standard deviation to the range as a measure of variability for quantitative data.

Consider the horizontal box plot shown below.


a.What is the median of the data set (approximately)?

b.What are the upper and lower quartiles of the data set (approximately)?

c.What is the interquartile range of the data set (approximately)?

d.Is the data set skewed to the left, skewed to the right, or symmetric?

e.What percentage of the measurements in the data set lie to the right of the median? To the left of the upper quartile?

f.Identify any outliers in the data.

Top credit card issuers, by region. The Nilson Report (December 2015) published a list of the top 150 credit card issuers worldwide. The issuers (e.g., American Express, MasterCard, Visa) were ranked based on outstanding debt during the year. The table gives a breakdown of the regions in the world served by the top 150 credit card issuers.

a. One of the top 150 credit card issuers is selected at random, and the region it serves is determined. What type of data (quantitative or qualitative) is measured?

b. For each region in the table, calculate the percentage of the 150 top credit card issuers that fall into that region.

c. Use the percentages, part b, to construct a relative frequency bar graph for the data summarized in the table.

d. Based on the bar graph, make a statement about the regions that most of the top 150 credit card users serve.

Permeability of sandstone during weathering.Refer to the Geographical Analysis(Vol. 42, 2010) study of the decay properties of sandstone when exposed to the weather, Exercises 2.47 and 2.65 (pp. 96 and 104). Recall that slices of sandstone blocks were measured for permeability under three conditions: no exposure to any type of weathering (A), repeatedly sprayed with a 10% salt solution (B), and soaked in a 10% salt solution and dried (C).

a.Combine the mean (from Exercise 2.47) and standard deviation (from Exercise 2.65) to make a statement about where most of the permeability measurements for Group A sandstone slices will fall. Which rule did you use to make this inference and why?

b.Repeat part afor Group B sandstone slices.

c.Repeat part afor Group C sandstone slices.

d.Based on all your analyses, which type of weathering (type A, B, or C) appears to result in faster decay (i.e., higher permeability measurements)?
