Results Study 3: You have noticed that people who attend the optional meditation classes seem more alert during the afternoon. You think that meditation improves alertness and focus and therefore, would have a speed advantage when completing jigsaw puzzles, compared to those who opted out of meditation sessions. You decide to investigate the impact of meditation on puzzle completion time. You collect data by recording who signed up for meditation class, and then record the time (minutes) it took for each person to complete the jigsaw puzzle activity.

Discussion Study 3: In this paragraph discuss the results and mention limitations or potential confounds that could explain the findings. Suggest how research on this question could be done better in future studies. In other words; how could you redesign the study to make it more experimental and to allow you to draw clearer conclusions?
Other Analyses: Finally, suggest two other research questions that could be tested using the variables in the data set. You don't have to run these but mention what could be tested and which t-test and variables you would use.
