Statistical measures bivariate regression and correlation

1. Correlation analysis

   • Statistical technique used to measure the closeness of the linear relationship between two or more variables on an interval scale.

2. Regression analysis

   • Statistical technique used to derive an equation that relates a criterion variable with one or more prediction variables
     • Analysis of simple regression
       • When only one is used predictor variable
     • Analysis of multiple regression
       • When two are used or more variables

3. Coefficient of correlation

   • Term used in regression analysis to designate the strength of the linear relationship between the criterion and predictor variables.

4. Coefficient of determination

   • Regression for denote the relative proportion of the total variation in the criterion variable
     • It can be explained by the fitted regression equation
