Thus, there are three categorical variables: Shoe Type (with 2 levels), Protection (with 4 levels)and Ankle Sprain (with 2 levels).
Read through the article before starting your analysis, to gain an understandingof the study that was done.
• In your report, identify what type of study this most closely resembles: an observationalstudy or a designed experiment. Provide a brief explanation of your decision.
• Summarize the variables “Ankle Sprain” and “Protection” in a contingency table, with thelevels of “Ankle Sprain” making up the rows and the levels of “Protection” making up thecolumns (that is, your table should have 2 rows and 4 columns, not including the rows fortotal or labels). Make sure your table has appropriate row and column labels. Include thistable in your report.
• Referring to the table you created, what can you observe about ankle sprains and the typeof protection players used? What conclusions, if any, might you be able to draw from this?Include your commentary in your report.
• Summarize the variables “Shoe Type” and “Ankle Sprain” in a side-by-side bar graph (hint:
you will have to create a contingency table of this data first!). There are two ways to do this:
(a) Compare shoe types (cushioned versus non-cushioned) within each level of ankle sprain(yes or no)
(b) Compare ankle sprains (yes versus no) within each level of shoe type (cushioned or noncushioned).
(c) If your goal is to compare the number of players who get ankle sprains within each shoetype, which option would be the most appropriate? Create the appropriate graph, andinclude it in your report.

• Referring to the graph you created, what can you conclude about the number of players whoget ankle sprains based on the shoe type they use? Include your commentary in your report.
• Using any relevant information from the analysis you have conducted above to support yourcomments, what does this data suggest about the patterns (if any) between shoe type, protection, and ankle sprains? Include your commentary in your report.
• An association for university soccer coaches would like to use the results of your report toinform their soccer players about what type of shoes and protection they should be using toavoid ankle sprains. What concerns, if any, do you have about this? Include your commentaryin your report.
