On this Picostat.com statistics page, you will find information about the modelcars data set which pertains to Model Car Data. The modelcars data set is found in the DAAG R package. You can load the modelcars data set in R by issuing the following command at the console data("modelcars"). This will load the data into a variable called modelcars. If R says the modelcars data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data.

Model Car Data

Description

The modelcars data frame has 12 rows and 2 columns. The data are for an experiment in which a model car was released three times at each of four different distances up a 20 degree ramp. The experimenter recorded distances traveled from the bottom of the ramp across a concrete floor.

Usage

modelcars

Format

This data frame contains the following columns:

distance.traveled

a numeric vector consisting of the lengths traveled (in cm)

starting.point

a numeric vector consisting of the distance of the starting point from the top of the ramp (in cm)

Source

Examples

plot(modelcars)
modelcars.lm <- lm(distance.traveled ~ starting.point, data=modelcars)
aov(modelcars.lm)
pause()print("Response Curves - Example 4.6")
attach(modelcars)
stripchart(distance.traveled ~ starting.point, vertical=TRUE, pch=15,
           xlab = "Distance up ramp", ylab="Distance traveled")
detach(modelcars)
