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?

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
