So far, we’ve been looking mostly at data where we have one measurement per subject, called a univariate data set. But often, we want to look at data sets where we have not one but two quantities, call them X and Y , for each subject, and we are interested in exploring whether there is a relationship between a subject’s X-value and the corresponding Y -value. This is called a bivariate data set.

摘要

So far, we’ve been looking mostly at data where we have one measurement per subject, called a univariate data set. But often, we want to look at data sets where we have not one but two quantities, call them X and Y , for each subject, and we are interested in exploring whether there is a relationship between a subject’s X-value and the corresponding Y -value. This is called a bivariate data set.
