This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, choi_2020_ednet.py. It is our best reading, not the source’s own codebook, and it may contain mistakes. Where the two disagree, the source data are the authority. If you find an error, please tell us.
| Column | What it is | Source column |
|---|---|---|
| IRW standard columns | ||
date | IRW standard Calendar time in seconds — either seconds elapsed since data collection start (relative) or Unix time (absolute). | made in the build script |
id | IRW standard Identifier for the focal unit being measured — typically a person, but sometimes another entity (e.g., a word in a lexical task). | made in the build script |
item | IRW standard Item identifier. | made in the build script |
item_family | IRW standard Groups items that may violate local independence — testlets, clones, or clusters of similar items. | made in the build script |
resp | IRW standard Response value. | made in the build script |
resp_raw | IRW standard The response as originally recorded, where resp holds a scored or recoded version of it — the letter a candidate marked (A–E), an option label, a categorical string. | made in the build script |
rt | IRW standard Response time. | made in the build script |
| Other columns | ||
itemcov_part | Not documented Covariates invariant to measurement probes (item-level attributes). | made in the build script |
What item codes and covariate values stand for is in the source’s README, README.md.
