The video tutorial introduces bivariate data, which involves two variables that may be dependent or independent. It explains how one quantity can be described in terms of another, using examples like paychecks and hours worked. The tutorial also covers the use of ordered pairs to represent these relationships and provides a table of values as an example. Additionally, it briefly touches on univariate data, which involves only one variable.

What is the role of the independent variable in a bivariate data set?
