Name at least one variable that we did not control for while conducting this experiment (i.e., a variable that we did not measure). Explain what it was and how it could have affected the results. Identify at least 2 potential limitations of this experiment, considering factors such as the duration of the study, sample size, use of controls, demographics of participants, and measurement protocol. Explain how each of these limitations might affect the interpretation and generalizability of the results. (You may find it helpful to review the Evaluating Experimental Design and Scientific Claims page as you write this response.). If you were to replicate this study to test this hypothesis, how could you improve the study design? Explain at least two changes that you would make and why they would improve the quality of this study from a scientific perspective. Incorporate statistical modeling in your answer.
