Background: Recovery curve after concussion for student-athletes The (fictitious) Midwest Journal of Medicine recently published a study of the recovery curve after concussions for student-athletes. Student-athletes complete a computer-based neurocognitive assessment when they first enter their university and are given a baseline concussion score. If a student-athlete becomes concussed, they are asked to perform the assessments again and again until their neurocognitive assessment score returns to their baseline score. You believe that hand dominance may have an impact on the study results and observe that this wasn’t controlled for in the original study. To show the importance of controlling for hand dominance when performing computer-based evaluations, you decide to conduct your own study among undergraduate students at UM.
Your Study: Effects of hand dominance on various computer-based activities for undergraduate students at UM. You have two different datasets available to you coming from a random sample of undergraduate students at UM. Each student was asked to perform a series of two computer-based activities that measure reaction time and memory. Each student performed each activity twice; first using their dominant hand and again using their non-dominant hand. You will be using these study results to evaluate if hand dominance has an effect on reaction time and memory when measured through these two computer-based activities.
Below is a summary of the data collected for each activity:
