When to use this
Use this immediately after upload and whenever coding changes.
Why it matters
Statistical procedures depend on both stored values and their substantive measurement meaning.
Step-by-step instructions
1. Open the dataset and select Variables.
2. Compare names and labels with the questionnaire.
3. Review detected data type and measurement level.
4. Mark identifiers and demographics.
5. Link indicators to approved constructs only when justified.
6. Confirm or correct classifications and record notes.
Expected outputs
Reviewed variable metadata linked to one immutable dataset version.
How to interpret the results
A numeric storage type does not automatically mean a variable is continuous. Treat Likert items according to the planned analysis and measurement rationale.
Common mistakes
Do not infer independent or dependent roles from column order. Do not treat identifier codes as measurements.
