## 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

W.J. Braun

### 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)
```
