Chapter 8 Comparing Two Independent Groups

Do male accountants earn different salaries than female accountants? Do people who are given a new shampoo use a different amount of shampoo than people who are given an old shampoo? Do cows that are fed a grain supplement and hay gain a different amount of weight than cows that are fed only hay?

These questions involve comparing two independent groups of data (as defined in the previous chapter). The variable that classifies the data into two groups should be nominal. The response variable can be ordinal or continuous, but must be numeric. This chapter discusses the following topics:

  • summarizing data from two independent groups
  • building a statistical test of hypothesis to compare the two groups
