Welcome
What are you trying to do?
Data I already have in psychology and behavioural science.
Your path
Create a study to hold it
A study is the container. You are not obliged to collect anything through ZStat.
Import the file
CSV for now, on the Data page. Leading zeros survive, and a column that is mostly numeric with a few words stays text rather than becoming numbers with holes in it.
Find out what you should be running
The guide for your field names the question in your own words and the procedure that answers it.
Analyse
Every result is stored with the digest of the data behind it, so you can prove later which version produced which figure.
What people in your field ask
Build the instrument - check it holds together - check it works the same in every group - then compare or model.
- Does my scale hang together?reliability
- Is it measuring one thing or several?efa
- Does the questionnaire mean the same thing to men and women?measurement invariance
- Did the intervention change anything?repeated measures anova
- Does X affect Y through M?mediation
Watch for: Reporting alpha as evidence of unidimensionality. It rises with the number of items and a twenty-item scale measuring two things easily exceeds .90.
