graphing a 3x2x2 mixed design in SPSS, how?


New Member


I have a 3-way mixed factorial data set. In this study, an experimenter compared three different therapies for quitting smoking; let's say they are X, Y, Z in two locations (Home and Work).
Therapy and location are both between subject variables. Participants were asked to rate their desire to smoke both (pre), and (post) quitting.

I wanted to graph this data in SPSS, so I clicked on:
Graphs -> legacy dialogs -> line

I didn't know exactly what to choose, but I tried both summaries for group of cases and of separate variables.
However, I got stuck in each one of them.

Could you please tell me which option to choose and where to put my variables to make a 3 separate graph for each therapy.

Thank you in advance.. :wave:
its been a while since i used spss, but i'm assuming you're using the GLM (univariate) procedure. If so, there should be an option there to output the graphs for you already.

Thanks james for helping out..

Yes, I'm using GLM, and as you said it has the plot option, but the problem is that when I produce the graphs from it, it is not flexible in editing the graph besides it doesn't allow showing the error bars!!
