  • 1.  Student on board with questions

    Posted Mon September 14, 2020 09:21 PM

    Hello, I am a student and I am very lost with using this software. I have watched many videos which is very helpful; however, I have one problem which is preventing me from moving forward. I completed a pre and a post study using survey monkey and selected SPSS the tab to download the data so that I could transfer it to the SPSS software, but when I opened it in the program the pre and the post survey collectors Numbers are combined or should I say directly follows each other. I am not sure if that is normal and if so, how can I interpret the data to show a change from the pre-test to the post-test?

    Usually there would be another variable to indicate which group a value is in, but it all depends on how you designed your survey. If the values are all pre/post/pre/post you can compute the group variable according to whether the case number (a special variable named $CASENUM) is odd or even. Use the mod function with modulus 2 to do this. (Start with the Transform > Compute menu).

    If all the pre values are followed by all the post values and, let's say, there are 100 of them, you could compute the group number like

    compute group = $CASENUM > 50.

    When i uploaded it into the spss software, the appear this way. The collectors number in vertical order where HINBI Pre-Test (A) the the different variables horizontally. After lets say 100 collectors HINBI Pre-Test (A) then the HINBI Post-Test (B) follows below.

    Do you have a video on doing this compute group = $CASENUM > 50.

    No. Maybe you should go through the help on using the Transform > Compute dialog. You can find it here.
