A researcher wants to study whether having to take a 4 hour driving safety course after you receive a traffic ticket can improve how safely a person drives. She compares a group of people who have received traffic tickets in Florida and who chose take a 4 hour driving safety course to a group of drivers who received a traffic ticket and opted to not take the course. She then measures whether they got a second traffic ticket within the next 6 months. 1. What is the independent variable for Scenario D? 2. How many levels are there for the independent variable in Scenario D? 3. What is the dependent variable for Scenario D? 4. What is the confound for Scenario D 5. How could the confound be fixed in Scenario D?
