r/spss

Hello, I'm doing a PROCESS moderation analysis with a categorical moderator on SPSS. The moderator is set to groups (i.e., group 1, group 2, group 3), and labelled 1 = low etc. I could be completely overthinking this, but do I still calculate the interaction term normally? Seems weird to me that the interaction term for group 3 will just be my IV x3.

If someone has a textbook or reference for this too, that would be greatly appreciated.

Hi everyone I am a masters student and I am currently cleaning my dataset and running tests. I want to be able to run multiple regression tests to do a mediation analysis, correlations, etc. and I need to create indexes. I was successful in creating two indexes each measuring attitudes on a 0 to 100 scale. However, I am having trouble creating indexes that are also measured on a 0 to 100 scale but they are based on a previous question that had respondents select multiple options (at least 3) which then those selected options popped up for the next few questions. Example: respondents chose which 3 podcasters from the list they listen to most often. Then the ones they chose appeared to which they measured how frequent they watch, how engaged they are when watching, etc. all on 0 to 100 scales.

I’ve tried computing these into indexes by the mean function mean.3(podfrequency1, podfrequency 2, etc.) but I think something is going wrong. When I run a frequency after my N decreases significantly. Also, when I try to do a reliability analysis with all the variables it can’t produce because it says N=0.

What am I doing wrong? Is the index even possible? Thank you so much!!!!

Hello, I am doing a research project, so basically im inputting information from qualtrics into spss.

The survey was done by having to answer prime questions before being randomly assigned one of the two scenarios, then answer some post scenario questions. From here i have to see which is a preference.

I need help understanding whether if i have to split the data by which scenario was assigned to get the average for the prime and responses, and for the Cronbach’s Alpha for both resulting in 4 Alphas in total.

I’m not sure if i make sense, but any help would be greatly appreciated!

UPDATE: i talked to a professor and unfortunately the data isn’t coherent enough to be tested, but thank y’all for the help it was very useful for me to learn more on how to use spss 😼

What am I doing wrong if I'm getting this error?
