In jverzani/UsingR: Data Sets, Etc. for the Text "Using R for Introductory Statistics", Second Edition

Description

Simulated data set investigating effects of cross-country ski-pole grip.

Usage

data(grip)

Format

A data frame with 36 observations on the following 4 variables.

UBP

Measurement of upper-body power

person

One of four skiers

grip.type

Either classic, modern, or integrated.

replicate

a numeric vector

Details

Based on a study originally described at http://www.montana.edu/wwwhhd/movementscilab/ and mentioned on http://www.xcskiworld.com/. The study investigated the effect of grip type on upper body power. As this influences performance in races, presumably a skier would prefer the grip that provides the best power output.
