Bug in repeated measures ANOVA SPSS 17?

[Joost van Ginkel]

I carried out a repeated measures ANOVA in SPSS 17. I didn't specify a measure name, and I got a warning message in the output that said that "The subcommand MEASURE is empty and will be ignored". SPSS performed the analysis but the titles of the plots all said: "Estimated Marginal Means of MEASURE_1". Since I wanted an appropriate variable name of the dependent variable in all the titles of my plots, I ran the analysis again, only now I specified a measure name too. But when I did that, SPSS added a second block of within subjects variables underneath the variables that I had already specified. Apparently, when you specify a variable name, SPSS 17 assumes that this dependent variable is added next to the default dependent variable MEASURE_1, thereby making it a MANOVA. Is this a bug in SPSS or am I missing something here?

Best regards,

Joost van Ginkel

Hi Joost.  I just tried the following with 17.0.2, and received no such warning.  In the tables and plot, the DV is called MEASURE_1, but IIRC, that has always been the case.

Cheers,

Strange, I've tried it again and the problem doesn't seem to occur
anymore. I guess I must have done something wrong. Anyway, thanks.
