+ | * If the independent variable X cannot significantly predict the dependent variable Y, it indicates that the change in Y is entirely due to random factors. If the independent variable X can significantly predict the dependent variable Y, then the explanatory variance of the independent variable X for the dependent variable Y should be significantly greater than the explanatory variance of the random factor for the dependent variable Y. | ||
