Reply Tofor My Two Group Design I Chose To Go With How Exercise Helps

For my two-group design, I chose to explore how exercise helps with energy levels after dinner. My study will include a control group that does not engage in exercise and reports their energy levels post-dinner. The independent variable (IV) in this two-group setup is the exercise level, with the control group not exercising (Level 1: No exercise) and the experimental group engaging in physical activity (Level 2: Exercise). The dependent variable (DV) is the energy level experienced after dinner.

To deepen the analysis and gain more nuanced insights, I plan to utilize a factorial design, specifically a 3x2x2 structure. This approach allows me to examine how multiple factors interact to influence post-dinner energy levels. The factors included are exercise frequency, diet quality, and age group.

The factorial design comprises the following variables:

  • IV1: Exercise Frequency
    • Level 1: 0 days/week
    • Level 2: 1-3 days/week
    • Level 3: 4-7 days/week
  • IV2: Healthy Meal Consumption
    • Level 1: 0-2 healthy meals/day
    • Level 2: 3-4 healthy meals/day
  • IV3: Age Groups
    • Level 1: 25-35 years
    • Level 2: 36-46 years

The dependent variable remains the same: energy levels after dinner.

I believe that utilizing a factorial design provides a comprehensive framework for understanding the complex interactions between these variables. It allows us to explore not just individual effects but also how these factors may synergistically influence energy levels. For example, it’s plausible that exercise benefits might be enhanced or diminished by dietary habits or age, and a factorial design can clearly elucidate such interactions.

By integrating these multiple variables, the research can move beyond a simplistic cause-effect relationship to a more detailed understanding of how lifestyle factors collectively impact energy. This approach aligns with the principles of experimental psychology as outlined by Myers and Hansen (2012), emphasizing the importance of multivariable analysis in behavioral research.
