Correlation.
Correlation and regression analysis are related in the sense that both deal with relationships among variables. The correlation coefficient is a measure of linear association between two variables. Values of the correlation coefficient are...
anything about causation. While we can determine positive and negative correlations, we do not know the cause-effect relationship between them. See Figure A-2, page 46 and Figure A-3, page 48. Experimental research reveals causality. But experimental method requires which conditions or variables are...
