This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, conner_2017_fruit.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 | ||
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). | ID |
item | IRW standard Item identifier. | made in the build script |
resp | IRW standard Response value. | made in the build script |
wave | IRW standard Longitudinal wave indicator. | made in the build script |
| Respondent covariates | ||
cov_age | Covariate | age |
cov_condition | Covariate 0 = Control · 1 = EMI · 2 = FV | condition |
cov_gender | Covariate 0 = Male · 1 = Females | gender |
cov_nz_european | Covariate 0 = New Zealand European or Other European · 1 = Other | NZEurop |
Covariate value labels are the source’s own, as the IRW recorded them. What item codes and any unlabelled values stand for is in the codebook released with the source data.
