Forbes' data on air pressure in the Alps and the boiling point of water (Weisberg, 1985).

Description

A data set on air pressure in the Alps and the boiling point of water (Weisberg, 1985). There are 17 observations on the boiling point of water at different pressures, obtained from measurements at a variety of elevations in the Alps. The purpose of the experiment was to allow prediction of pressure from boiling point, which is easily measured, and so to provide an estimate of altitude: the higher the altitude, the lower the pressure. The dataset is characterized by one clear outlier.

Usage

Format

• x: boiling point

• y: 100 x log(pressure)
