Bivariate Data
Definition
Bivariate data refers to a set of data that involves two variables, where each observation has a pair of values. It allows for the analysis and comparison of how the two variables are related or correlated.
Analogy
Think of bivariate data as a dance floor with couples dancing together. Each couple represents an observation, and their movements represent the values of the two variables being studied. By analyzing their dance moves, we can understand how the variables interact.

Categorical Variables: Categorical variables are types of variables that represent qualitative characteristics or attributes. They divide observations into distinct groups or categories.
Two-Way Tables: Two-way tables are used to organize categorical data by displaying it in rows and columns. They provide a way to analyze relationships between two categorical variables by showing frequencies or percentages in each cell.
Scatterplots: Scatterplots are graphical representations of bivariate data, where each point on the plot represents an observation with its corresponding values for both variables. They help visualize patterns and relationships between the two variables.
