CHAPTER 14 Cooperative Group Activities 723 • Find the marriage rate per 10,000 population for several years. Assume that in each year 10,000 people were randomly selected and surveyed to determine whether they were married. Use a p chart to test for statistical stability of the marriage rate. (Other possible rates: death, accident fatality, crime.) • Search the Internet and find the numbers of runs scored by your favorite baseball team in recent games, then use run and control charts to explore statistical control. 2. In-class activity If the instructor can distribute the numbers of absences for each class meeting, groups of three or four students can analyze them for statistical stability and make recommendations based on the conclusions. 3. Out-of-class activity Conduct research to find a description of Deming’s funnel experiment, then use a funnel and marbles to collect data for the different rules for adjusting the funnel location. Construct appropriate control charts for the different rules of funnel adjustment. What does the funnel experiment illustrate? What do you conclude? 4. Out-of-class activity This chapter included annual global mean temperatures and annual carbon dioxide amounts. Identify another factor that should be considered in an investigation of global warming. Find annual data and use the methods of this chapter to conduct an analysis.
