This dataset is designed for teaching logistics regression. The dataset is a subset of data derived from the 2007 School Readiness Survey, and the example examines whether or not young children know all or most of the letters of the alphabet, and if that is predicted by their TV viewing, their age, and whether their parents read to them. The dataset file is accompanied by a teaching guide, a student guide, and a how-to guide for R.
