chapter_12_exercise_23: The data used in Chapter 12, Exercise 23

Description

Data from Chapter 12 Exercise 23 of Designing Experiments and Analyzing Data: A Model Comparison Perspective (4th edition; Maxwell, Delaney, & Kelley). The one-week follow-up to the Hu et al. (2015) sleep study of Exercise 22, adding a delayed measurement so that each participant now has six bias scores (cued and uncued, at prenap, postnap, and one-week delayed). Two of the 40 participants lacked delayed scores, so this data set has 38 rows. The exercise analyzes the scores as a 2 (cuing) by 3 (time) fully within-subjects design; lower scores indicate less bias.
