REFRIGERATOR: Refrigerator Energy Consumption

In alanarnholt/PASWR2: Probability and Statistics with R, Second Edition

Refrigerator Energy Consumption

Description

Sixty 18 cubic feet refrigerators were randomly selected from a company's warehouse. The first thirty had their motors modified while the last thirty were left intact. The energy consumption (kilowatts) for a 24 hour period for each refrigerator was recorded and stored in the variable kilowatts.

Usage

REFRIGERATOR

Format

A data frame with 60 observations on the following 2 variables:

• kilowatts (energy consumption in kilowatts for a 24 hour period)

• group (factor with levels original and modified)

Examples

# Boxplot
ggplot(data = REFRIGERATOR, aes(x = group, y = kilowatts)) + geom_boxplot()
ggplot(data = REFRIGERATOR, aes(x = group, y = kilowatts, fill = group)) + 
geom_boxplot() + labs(y = "energy consumption in kilowatts for a 24 hour period") + 
guides(fill = "none") + scale_fill_brewer()
