Bivariate statistical measures regression and correlation

1. frequency table or contingency table

2. regression and correlation : Correlation quantifies how related two variables are, while linear regression consists of generating an equation (model) that, based on the relationship between the two variables, makes it possible to predict the value of one from the other.

3. Correlation: is a statistical measure that expresses the extent to which two variables are linearly related (that is, they change together at a constant rate). It is a common tool for describing simple relationships without making statements about cause and effect.

4. In statistics, regression analysis is a statistical process for estimating relationships between variables. It includes many techniques for the modeling and analysis of various variables, when the focus is on the relationship between a dependent variable and one or more independent variables.

5. Bivariate statistical measures: Bivariate statistical techniques allow the joint analysis of two characteristics of individuals in a population with the purpose of detecting possible relationships between them.
