The complexity of bivariate data examples is the use of two complex sets that are always dependent on what is being used. A good bivariate data example is the sales of ice-cold drinks depending on the weather and the heat or the cold of the day. The same can be said about finding statistical answers to the questions based on what equation is being used like finding positive or negative sides. Choosing two columns by using graphs and calculations will help you address all bivariate data questions that you will encounter below to find the best solutions to your problem.
