Stretch of hot pizza cheese

Format

A data frame with 30 observations on the following 3 variables.

• temp: a numeric vector
• cheese: a numeric vector
• stretch: a numeric vector

Details

A critical quality measure of pizza cheese is how well it stretches when it is hot. This study was to evaluate the amount of cheese and the temperature at which the pizza was cooked on the stretch of the hot cheese. Measuring the stretch of pizza cheese is not a precise science, thus, five measurements were taken on each pizza. One pizza was used for each temperature/cheese combination.
