A basic experiment
ToothGrowth is a built-in R dataset from a study that examined the effect of three different doses of Vitamin C on the length of the odontoplasts, the cells responsible for teeth growth in 60 guinea pigs, where tooth length was the measured outcome variable.
Let's load ToothGrowth into our environment,do some exploratory data analysis, and perform a t-test to get an idea of the purpose of a basic experiment.
