## 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.
