CASE STUDY Reputations of Companies in the U.S. 16 CHAPTER 1 Introduction to Statistics For more than 50 years, The Harris Poll has conducted surveys using a representative sample of people in the United States. The surveys have been used to represent the opinions of people in the United States on many subjects, such as health, politics, the U.S. economy, and sports. Since 1999, The Harris Poll has conducted an annual survey to measure the reputations of the most visible companies in the United States, as perceived by U.S. adults. The Harris Poll used a sample of 34,026 U.S. adults for the 2020 survey. The survey respondents rate companies according to key attributes that are classified into seven categories: (1) trust, (2) vision, (3) growth, (4) products and services, (5) culture, (6) ethics, and (7) citizenship. This information is used to determine the reputation of a company as Excellent, Very Good, Good, Fair, Poor, or Very Poor. The reputations (along with some additional information) of 10 companies are shown in the table. 1.
