I wanted answers for these questions in relation to this article : https://academic.oup.com/ptj/article/79/10/906/2842426

Questions:

1. Name each statistical analysis used and identify what hypothesis the analysis was used to test.
2. If additional statistics (e.g. descriptives) were used, name these and describe why they were used.
3. If any data visualizations were used, name the graph and explain why this graph was the best way to display the data (or, if you feel another type of graph would have been better, tell me why).
4. Choose one statistical analysis (i.e. correlation, t-test, regression, or ANOVA) and name all the assumptions necessary for that test. Were these assumptions mentioned in the article? Which ones?
5. Given the data described in the paper, what is one analysis that the authors did not test that you could test? Name the variables used, which variable(s) would be independent? Which would be dependent? What is the name of the analysis and why is that the correct analysis to use to look at the data you chose?
