## 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.
