Explanation The Pew Research poll results on the political affiliation and education attainment is given. The chi-square test of independence is used to determine whether there is association between political party affiliation and education attainment. The test is performed through the following steps: Step 1: Hypothesize. H 0 : Political party affiliation and education are independent (not associated). H a : Political party affiliation and education are not independent (are associated). Step 2: Prepare. The chi-square test of independence can be used to test the association because the data is randomly taken from one random sample, which consists of people of two categorical variables. The expected counts are calculated and checked if all the expected counts are 5 or more. Use Minitab to calculate these expected counts and determine whether each expected count is greater than 5. Software procedure: Step by step procedure to perform chi-square test using Minitab is as follows: Enter the data summary including the optional row and column labels in the worksheet. Choose Stat > Tables > Cross Tabulation and Chi-Square . In the dialog opened, choose Summarized data in a two-way ta ble . For Columns containing the table: select both the columns by double clicking the column names. For Rows: select C1. Click Chi-square. In the dialog opened, check Chi-square test and Expected cell counts. Click Ok. Click Ok . The table of observed and expected counts (in parenthesis) is obtained as, Political party affiliation Political party affiliation Educational Attainment Democrat/Lean Democrat Republican/Lean Republican Total High school or less 144 160
