Suppose we have a dataset containing a number of body measurements from a population of people.Each record in the dataset contains all of the body measurements from a single person.We wish to follow up on the conjecture that typically a person's right wrist will be greater in diameter than his or her left wrist because of the larger amount of use of the right hand by the majority of people.
