Gartlett & Bos (2010) presented data on the outcomes of male and female children raised by same-sex (lesbian) parents and those raised by opposite-sex parents. In a longitudinal study following 78 children of same-sex parents for 17 years, she collected data on Achenbach’s Child Behavior Checklist when the children were 17. She used an equal sample of raw data from normative data collected by Achenbach on a random sample of children. For convenience we will assume that each cell contained 43 children. The data are shown below.

Compute an analysis of variance on these data and interpret the results. (Higher scores reflect greater competence.) (The F values differ somewhat from hers because she analysed the data with a multivariate analysis of variance, but the means agree with hers. An SPSS version of data with these means and variances is available on the Web as Ex13-31.sav.)
