Question

Scenario 2: A study was conducted to determine the effecet of several diffrent physical therapy treatments on flexibility in patients after rotator cuff surgery. Patients were randomly assigned to one of the three physical therapy treatments and the researchers recorded the range of arm motion for the patients. Research Question: Is there a difference in the mean range of arm motion for post-surgical patients under the three physical therapy treatments? a. Identify the independent and dependent variables for this study. (2 pts.) Independent: The independent variable is the three different physical therapy treatment. Dependent: The dependent variable is the range of arm motion for the patients. b. Is this an example of a One Way ANOVA design or a Repeated Measures ANOVA design? Justify your response. (3 pts.)

Explanation / Answer

Sol:

I think there is a difference in mean range of arm for post surgical patients under three different phyical therapy treatments because patients were assigned randomly to three different therapy treatments.

a) Independent variable is three different Physical therapy treatments. Dependent variable is the range of arm motion for the patients.

b) it think it is one way ANOVA design,because we can find the difference in mean range of arm post surgical treatments.
