Textbook Question

Chapter 12, Problem 40PS

Brand valuations are critical to CEOs, financial and marketing executives, security analysts, institutional investors, and others who depend on well-researched, reliable information for assessments and comparisons in decision making. WPP and Millward Brown annually publish the BrandZ Top 100 Most valuable Global Brands. The Brads. The BrandZ rankings combines consumers measures of brand equity with financial measures to establish a brand value for each brand. The file BrandZTechFin contains the 2016 brand values for technology sector and the financial institutions sector.

a. Using a 0.05 level of significance, is there evidence of a difference in the median brand value between the two sectors?

b. What assumptions must you make in (a)?

c. Compare the results of (a) with those of Problem 10.17 on page 361. Discuss.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
