A high school teacher is attempting to determine the best way to teach students about sexually transmitted diseases (STDs). One-third of the students are asked to read textbook information on STDs, a second third are asked to google information, and the remaining third are provided with real-life examples (i.e., "this is how I got my STD stories") to read. Half of the students in each of these groups are asked to discuss what they read with a peer, while the other half are asked to discuss what they read with an adult. One week later, the teacher gives the student a test to determine how the type of material presented and the age of the discussant impacted their score on the test (max score = 40). Each participant was in only one condition.   How many independent variables were in this experiment? What are they? How many levels does each variable have? Is each variable a within- or between-subjects variable?    This experiment is a ___________ design (circle one). Between-subjects           Within-subjects           Mixed
