Explain these questions following Instructions using one of these designs for each of the exercises below 1. Time-Series Design (any variation) 2. Nonequivalent Control Group Design 3. Pretest Posttest Control Group Design 4. Posttest Only Control Group Design 5.Solomon Four Group Design Then Answer the other questions for each exercise. Example: Exposure to a Film about Migration and Immigration Attitudes Social or Public Health Issue: Migration documentary and immigration attitudes Instructions: Design an experimental study to investigate these variables. 1. What is your hypothesis? Watching a documentary favorable to migration increases positive immigration attitudes. 2. What is your independent variable? Migration documentary 3. What is your dependent variable? Positive immigration attitudes 4. Which experimental design are you thinking of using? Why? (More than one correct answer exists. Here is an example.) Pretest Posttest Control Group Design. This design will help determine if the experimental group participants' attitudes shifted after viewing the documentary because those posttest results can be compared to their pretest results. Their posttest results can also be compared to a control group's test results who saw an innocuous film not related to immigration.

Exercise 1A: Listening to Heavy Metal Music and Aggression Social or Public Health Issue: Heavy metal music and aggressive behavior Instructions: Design an experimental study to investigate these variables. 1. What is your hypothesis? 2. What is your independent variable? 3. What is your dependent variable? 4. Which experimental design are you thinking of using? Why? 5. How is this experimental design notated?

Exercise 1B: Use of Social Media and Interpersonal Relationship Maintenance Social or Public Health Issue: The use of social media and interpersonal relationship maintenance with friends and family among long-term teenage hospital patients. Hint: Convert the "use of social media" into a non-continuous, binary variable by having a cutoff. For example: o Experimental Group: "High users" use social media for 1 hour or more a day. o Comparison Group: "Low users" use social media less than 1 hour a day. Instructions: Design an experimental study to investigate these variables. 1. What is your hypothesis? 2. What is your independent variable? 3. What is your dependent variable? 4. Which experimental design are you thinking of using? Why? 5. How is this experimental design notated?
