Student Risk Taking
Students were administered two parallel forms of a test after a random assignment to three different treatments.
data("students")A data frame with 35 observations on the following 3 variables.
treatmenta factor with levels AA, C, and
NC.
lowthe result of the first test.
highthe result of the second test.
The data arise from a large study of risk taking (Timm, 2002).
Students were randomly assigned to three different
treatments labelled AA, C and NC. Students were administered two
parallel forms of a test called low and high. The aim is to
carry out a test of the equality of the bivariate means of each treatment
population.
