Rugby Injuries
Knee injuries are a major problem for athletes in many contact sports. However, athletes who play certain positions are more prone to get knee injuries than other players, and their injuries tend to be more severe. The prevalence and patterns of knee injuries among women collegiate rugby players were investigated using a sample questionnaire, to which 42 rugby clubs responded.21 A total of 76 knee injuries were classified by type as well as the position (forward or back) of the player.

Chi-Square Test: Men Tear, MCL Tear, ACL Tear, Patella, PCL Tear

a. Use the MINITAB printout to determine whether there is a difference in the distribution of injury types for rugby backs and forwards. Have any of the assumptions necessary for the chi-square test been violated? What effect will this have on the magnitude of the test statistic?

b. The investigators report a significant difference in the proportion of MCL tears for the two positions (P < .05)="" and="" a="" significant="" difference="" in="" the="" proportion="" of="" acl="" tears="" (p="">< .05),="" but="" indicate="" that="" all="" other="" injuries="" occur="" with="" equal="" frequency="" for="" the="" two="" positions.="" do="" you="" agree="" with="" those="" conclusions?="">
