    Help With Repeated Measures ANOVA




    Okay, so I have got 15 subjects, who had to perform a repeated sprint test (5 sprints) twice one with a supplement then the other with a placebo the following week.

    I now have times for with supplement and placebo for every single subject and need to perform an analysis using SPSS.

    I believe I need to perform a repeated measures ANOVA?

    In Data View I have got the following

    A Time 1 Time 2 Time 3 Time 4 Time 5

    1.00 5.483 6.114 5.246 6.195 6.669
    1.00 5.594 6.244 5.402 5.719 5.645
    1.00 5.987 5.707 5.529 6.760 5.512
    1.00 5.669 5.628 5.828 5.796 5.764
    1.00 8.444 6.391 6.740 6.396 6.189
    1.00 5.898 5.167 6.729 5.313 6.047
    1.00 5.752 5.315 5.641 5.987 5.551
    1.00 5.376 6.013 5.115 5.167 5.758
    1.00 6.366 6.848 6.552 6.875 6.977
    1.00 6.536 6.580 7.231 6.415 7.172
    1.00 5.490 5.157 6.309 5.263 5.539
    1.00 6.233 6.219 6.196 6.163 6.099
    2.00 6.098 5.720 5.984 5.986 6.169
    2.00 5.445 5.656 5.801 5.928 5.518
    2.00 5.320 5.669 5.870 5.321 6.460
    2.00 5.293 5.472 5.953 5.458 5.612
    2.00 6.417 6.501 6.523 6.399 6.276
    2.00 5.411 5.653 5.730 5.577 5.853
    2.00 5.195 5.217 5.471 5.413 8.622
    2.00 5.853 5.182 5.560 5.891 5.412
    2.00 8.281 6.798 6.671 6.509 6.690
    2.00 6.885 6.687 6.955 6.743 6.887
    2.00 5.196 5.844 6.024 6.057 5.137
    2.00 6.963 6.873 7.545 6.302 6.360

    Where 1.00 is with and 2.00 is placebo

    Is this right to start with?

    Re: Help With Repeated Measures ANOVA

    For SPSS repeated mesaures analysis of variance, all data from one and the same subject are contained in 1 line. You need 10 variables, something like placebo1 , ... ,placebo5, verum1,... , verum5

    With kind regards
