Question
**"What if I told you, you can go to the gym without telling everyone on facebook about it"**
You want to know if people are more likely to make a behavioral change (like sticking to an exercise regime), if they announce it publicly
1. Design an independent groups (between subjects) experiment to test this. You may choose the behavior to change (exercise, too much Facebook, smoking, procrastinating your weekly module assignments, etc.).
Include the following: How you assigned participants to groups. The levels of the independent variable and how you manipulated them. The dependent variable and how you measured it.
2. Now, design a repeated measures (within subjects) experiment to test this.
Include the following: The levels of the independent variable and how you manipulated them. How you controlled for order effects. The dependent variable and how you measured it.
Explanation / Answer
1. The behaviour that is targeted alcohol consumption during weekdays. Individuals who report that they consume alcohol during weekdays will be identified and recruited. The experimental and control groups will then be established, to which the participants will be randomly assigned. The experimental group will be asked to update a status on Facebook every week with respect to their decision of not consuming alcohol during weekdays. The control group, on the other hand, will be instructed to post about current affairs. This practice will be tracked over three months. Data from both the groups will be collected with respect to their alcohol consumption on weekdays and compared to check if any significant differences exist.
2. In the repeated measures design, data with respect to the participants reported consumption of alcohol during weekdays will be collected. For the next three months, the participants will be asked to update a status on Facebook every week about their resolve. After the passage of three months, data from participants with respect to alcohol consumption will be collected again. This data would then be compared to the data collected previously in order to check if any significant changes have occurred.
