ANOVA repeated measures - SPSS

[cvlm]

Hello,

I am C Menon, a student & wish to know how I could effectively use Repeated measures ANOVA using SPSS for the following scenario (I shall provide a similar example directly).

I have coached 20 students “a particular method of learning” (say, problem based learning). I conducted examination 3 times; “before enrolment, 1 and 2 months later”. Same type of coaching was done for 5 different subjects (example maths, science, etc).

I wish to know (a) how the students performed based on their marks (b) whether my coaching technique is good for every subject (or only for some subjects).

Questions are:

Currently I use repeated measures ANOVA (SPSS) for each subject separately & I understand the results. However, I wish to know how I can combine all subjects together when analyzing? What do I do differently in SPSS? Combining it helps me find the interactions, doesn’t it?

Thanks very much in advance!

create a new variable of subjects and enter the code
e.g. for maths 1, physics 2, etc.
and then use this variable in MANOVA
