Thank you for reading this plea for help and apologies for my rudimentary descriptions.
I have only just started doing some SPSS for my PhD in education. I have the following data sets:
Batch number of questionnaire (of 2; beginning and end of the year),
Type of student (intervention; one year after intervention; control),
gender and year group
I have measured how students feel about writing on five different scales, ranging from 1 (f.e.happy) to 5 (f.e. unhappy).
I am now trying to find out whether students of a particular gender and/or year group feel differently at the end of the year, depending on which group they belong to. For example:
- the changes between (batch 1 + intervention + boy) = x mean feeling VS (batch 2 + intervention + boy) = x mean feeling
I have got the means of these groups (see screenshot attached) but unfortunately I can't figure out how to run a t-test or an anova which can tell me about the significance of the changes- and which changes are the ones that I should take seriously.
I would be most grateful for some pointers; this has been doing my head in for a couple of weeks now and unfortunately both my supervisor and my uni are unable to help.
