Bivariate Variable

Definition

A bivariate variable is a type of variable that involves two variables and examines their relationship with each other. It explores how changes in one variable affect the other.

Analogy

Think of a bivariate variable as a seesaw. The position of one person on the seesaw affects the position of the other person. If one person moves up, the other person moves down. Similarly, changes in one variable can impact the values or behavior of another variable.

Categorical Variable: A categorical variable can be one of the variables involved in a bivariate analysis, where its categories are compared to another variable.

Scatterplot: A scatterplot is a graphical representation used to display bivariate data. It shows how two variables are related by plotting their values on a coordinate plane.

Correlation Coefficient: The correlation coefficient measures the strength and direction of the linear relationship between two quantitative variables. It ranges from -1 to 1, where -1 indicates a perfect negative relationship, 0 indicates no relationship, and 1 indicates a perfect positive relationship.
