Example#1; A researcher wishes to examine whether time ofday (morning versus afternoon) affects the memory of older and younger participants. He obtains a sample of 40 older individuals and 40 younger individuals and gives them a passage to read. They are later given a test over the passage (scores on the test could range from O to 30). HaJfofthe individuals are randomly assigned to read the passage and take the test in the morning, and the other half do so in the afternoon. The data are reported in the table below (the numbers represent mean test scores for each group; that is, “M" is mean). Morning Testing М-15 Afternoon Testing Older Adults М-8 Younger Adults M= 16 М-20 2. Name the other independent variable. a. Does this IV represent independent groups or correlated groups? b. How many levels does this IV have?
