    Choice of Test for research data in Femur bone fracture analysis.




    Hello ,

    I am Using SPSS on Windows 8 and SPSS Version 20.

    I have data regarding the Femur bone fracture strength on patients with Hip and knee prosthesis .

    I need to determine if the distance between the tips of the prosthesis has an effect on the fracture strength(continuous) . there are 3 fixed distances (i.e : nominal variable).

    Also have data regarding the Bone mass density want to analyse if this has an effect too.

    So what tests would be suitable for this analysis.

    Thanks for your help.

    For a simple analysis, you could use a 1-way between subjects analysis of variance. You're independent variable would be the Distance (3 levels) and the outcome would be your continuous fracture score. This will allow you to answer questions like whether there are significant mean differences between the 3 levels with respect to fracture scores.

    If you would like to examine other effects in the context of the Distance variable, you can extend this to a multiple linear regression model. Similar questions can be answered like above, too.

    Hope this helps,

    Cheers

    Re: Choice of Test for research data in Femur bone fracture analysis.

    For the second part I need to decide whether the specific parameters of each bone (cortical thickness, cortical area,
    bone mineral densities) influence the comparison. Could you suggest an appropriate test.

    Would it be appropriate to use the ANCOVA test for this.?

    If these are predictor variables then you can use either multiple regression or ANCOVA (which essentially is multiple regression).
