## 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.
