Q1 Intuit, maker of Quicken, QuickBooks, and Turbo Tax software for accounting and tax preparation, has enjoyed years of growth and profits, thanks in part to its efforts to learn what customers want. One of its most important marketing research tools is called a "net promoter survey." That survey is extremely simple. Researchers simply ask customers face to face, "On a scale of 0 to 10 [with 10 being most likely], how likely is it that you would recommend our product to your friends or colleagues?" Customers who respond with a 9 or 10 are called "promoters," and customers who respond with through 6 are called "detractors." Subtracting the percentage of respondents who are detractors from the percentage who are promoters yields the net promoter score. Intuit's CEO, Steve Bennett, who says he believes that "anything that can be measured can be improved"encourages the ongoing collection of net promoter scores as a way to improve products and customer service and thereby build revenues and profits. Of course, making improvements requires that the company not only know whether customers are satisfied or dissatisfied but also know why. To learn more and in order to protect their identity, the company asks survey respondents who are promoters to go online and provide more detailed opinions. For example, Intuit learned that claiming rebates was an annoying process (the company has simplified it) and that discount stores were offering some products for less than the prices offered online to frequent buyers (the company plans to adjust prices) a) While conducting the "net promoter survey", the research coordinator believed that random sampling error was going to occur. Critically evaluate and determine why that is the case or not? (1 Mark) b) Jane and John are among the employees who are tasked to conduct the interviews. John always get an extremely higher promoter score compared to Jane whenever the 2 conduct the survey separately. The research coordinator does not suspect John of cheating with the survey data but rather attributes it to John's personality while conducting the interview on the answers he gets. Explain what types of error could be associated with John? (1 Mark)
