This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, content_literacy_intervention.R. 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 | ||
block_id | IRW standard The level above cluster_id — in a randomised design, the block or stratum within which assignment was made (treat varies within a block, and clusters nest in blocks). | not traced |
cluster_id | IRW standard The group a focal unit is nested in — classroom, teacher, school. | not traced |
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. | s_q_num |
resp | IRW standard Response value. | s_correct |
std_baseline | IRW standard A standardised pre-treatment score, usually the trial's baseline measure. | not traced |
treat | IRW standard Treatment group assignment in experimental studies. | s_itt_consented |
| Respondent covariates | ||
cov_asian_num | Covariate | not traced |
