ABSTRACT
This chapter reanalyzes a number of datasets discussed in previous chapters and, in addition, describes the analysis of a new dataset given in Aitkin (1978). These data come from a sociological study of Australian aboriginal and white children. The sample included children from four age groups (final year in primary school and first three years in secondary school) who were classified as slow or average learners. The number of days absent from school during the school year was recorded for each child. The data are given in Table 7.1. The variables are as follows:
eth: ethnic group (A=aboriginal, N=white)
sex: sex (M=male, F=female)
age: class in school (F0, F1, F2, F3)
lrn: average or slow learner (SL=slow learner, AL=average learner)
days: number of days absent from school in one year
One aim of the analysis is to investigate ethnic differences in the mean number of days absent from school while controlling for the other potential predictors sex, age, and lrn.
