The correct answer is: A. independent variable
An independent variable is a variable that is changed by the experimenter to see how it affects the dependent variable. In regression analysis, the independent variable is the variable that is plotted on the x-axis, and the dependent variable is the variable that is plotted on the y-axis.
The significance of an independent variable is determined by the p-value. The p-value is the probability of obtaining the results that were observed if the null hypothesis were true. A low p-value indicates that the results are statistically significant, and that the independent variable is likely to have a real effect on the dependent variable.
The significance of a dependent variable is not typically considered in regression analysis. This is because the
