The regression for this set of dependent and independent variables proves that the independent variable is a good predictor of the dependent variable with a reasonably high coefficient of determination Coefficient Of Determination Coefficient of determination, also known as R Squared determines the extent of the variance of the dependent variable which can be explained by the independent variable. The dependent variable in this regression equation is the distance covered by the truck driver, and the independent variable is the age of the truck driver. In this particular example, we will see which variable is the dependent variable and which variable is the independent variable. The regression analysis formula for the above example will be It can be manually enabled from the addins section of the files tab by clicking on manage addins, and then checking analysis toolpak. For the further procedure of calculation, refer to the given article here – Analysis ToolPak in Excel Analysis ToolPak In Excel Excel's data analysis toolpak can be used by users to perform data analysis and other important calculations. The regression analysis equation is the same as the equation for a line which isįor the calculation of Regression Analysis, go to the Data tab in excel, and then select the data analysis option. It helps in the process of validating whether the predictor variables are good enough to help in predicting the dependent variable.Ī regression analysis formula tries to find the best fit line for the dependent variable with the help of the independent variables. In order to predict the dependent variable, one or multiple independent variables are chosen, which can help in predicting the dependent variable. While running a regression analysis, the main purpose of the researcher is to find out the relationship between the dependent variable and the independent variable. Regression is a statistical tool to predict the dependent variable with the help of one or more than one independent variable. Regression analysis is the analysis of relationship between dependent and independent variable as it depicts how dependent variable will change when one or more independent variable changes due to factors, formula for calculating it is Y = a + bX + E, where Y is dependent variable, X is independent variable, a is intercept, b is slope and E is residual.
