(Package: WWGbook) :
ratpup data in Chapter 3
The data come from a study in which 30 female rats were randomly assigned to receive one of three doses (High, Low, or Control) of an experimental compound.
The data used in this example were originally reported by Douglas, et al. (2004). The aim of their experiment was to examine nucleotide activation (guanine nucleotide bonding) in seven different brain nuclei (i.e., brain regions) among five adult male rats.
The Study of Instructional Improvement (SII; Hill, Rowan, and Ball, 2004) was carried out by researchers at the University of Michigan to study the math achievement scores of first- and third-grade students in randomly selected classrooms from a national U.S. sample of elementary schools.
