Student Risk Taking

Description

Students were administered two parallel forms of a test after a random assignment to three different treatments.

Usage

data("students")

Format

A data frame with 35 observations on the following 3 variables.

treatment: a factor with levels AA, C, and NC.
low: the result of the first test.
high: the result of the second test.

Details

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.
