Codebook

This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, content_literacy_intervention_g1.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
`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.	`item_id`
`resp`	IRW standard Response value.	made in the build script
`treat`	IRW standard Treatment group assignment in experimental studies.	`s_itt_consented`

What item codes and covariate values stand for is in the codebook released with the source data.
