Bivariate statistical measures of regression and correlation

Bivariate statistical measures of regression and correlation

1. Correlation analysis

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

2. Correlation coefficient

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

3. Coefficient of determination

   • Regression analysis to determine the relative proportion of the total variation in the criterion variable. Can be explained by the fitted regression equation

4. Regression analysis

   • Statistical technique used to derive an equation that relates a criterion variable to one or more predictor variables
     • There are two types of regression analysis
       • Multiple regression analysis
         • When two or more variables are used
       • Simple regression analysis
         • When only one prediction variable is used
