Hi,
I conducted an experiment in which participants played the same game three times using different interaction techniques (different one each time). During the game they had to complete a series of task, with the time taken to complete each task recorded. I have done a one-way repeated measures anova to analyse the effect of each technique on game completion time. I'm now trying to look at the effect of each technique on the time taken to complete each task, so i can see where the techniques "worked" and where they "didn't". I'm new to anova and SPSS so i'm not sure whether such an analysis would be one-way or two and whether it would be repeated-measures or not.
Any help would be much appreciated :)
P.S. i'm not sure how to respond or comment on answers on here so if anyone could tell me how i do that, it would be great.
I am not sure about your design so I suggest that you look at the repeated measures material in the link. If I was doing it I think I would model it as a linear mixed model which is in the notes for Chapter 6. DV would be time.

PS I would not use SPSS. R is a free download. The Rcommander package is a point and click GUI. Book attached.
