Organizing your data in SPSS? Here’s the rule: one row = one person. Outcomes in one column. Group labels in another. Numbers are numbers (Scale). Names are names (Nominal). That’s it. Most “mystery errors” happen when headers get pasted as data and then numbers sneak in as text. Clean structure makes analysis boring… in the best way. If your sheet reads like a tidy roster, your tests will run like a tidy story.
