In seonghobae/flirt.x32: Flexible Item Response Theory Modeling

Description

This data come from the British sample of the 1992 Eurobarometer Survey (Reif and Melich, 1992) on perceptions of science and technology provided by Bartholomew et al. (2008). There are seven statements (such as ‘Science and technology are making our lives healthier, easier, and more comfortable’) and the response categories are ‘strongly disagree’, 'disagree to some extent', ‘agree to some extent’, and ‘strongly agree’.

Bartholomew et al. (2008) considered a between-item two-dimensional generalized partial credit model by using two item clusters, 1) items 1, 3, 4, and 7, and 2) items 2, 5, and 6.

Format

A data frame with 392 observations with 7 items. Each item has five response categories from ‘strongly disagree’ to ‘strongly agree’.
