variables for correlating two phenomenon, it is essential that the two phenomenon should have cause-effect relationship,& if such relationship does not exist then the two phenomenon can not be correlated. ? If two variables vary in such a way that movement in one are accompanied by movement in other, these variables.
Simple regression. 1. Regression is the analysis of the relation between one variable and some other variable(s), assuming a linear relation. Also referred to as least squares regression and ordinary least squares (OLS). The parameters in a simple regression equation are the slope (b1) and the intercept (b0): yi = b0 + b1
