Bivariate statistical measures regression and correlation

Bivariate statistical measures regression and correlation

1. Correlation analysis measures the closeness of the relationship between two or more variables considering the joint variation of the two measurements, neither of which is subject to restriction by the experimenter.

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

3. Regression analysis is used to derive an equation that relates the criterion variable to one or more predictor variables. In this, the frequency distribution of the criterion variable is considered when one or more of the prediction variables are kept fixed at various values.

4. Determination coefficient Term used in regression analysis to denote the relative proportion of the total variation in the criterion variable that can be explained by the fitted regression equation.
