Student Risk Taking
Students were administered two parallel forms of a test after a random
assignment to three different treatments.
A data frame with 35 observations on the following 3 variables.
a factor with levels
the result of the first test.
the 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
high. The aim is to
carry out a test of the equality of the bivariate means of each treatment
