SS MS Regression 3 1,116,743 372,248 Error 22 361,422 16,428 Total 25 1,478,165 The degrees of freedom for the F test is (3,22). Step 2 b) Critical value: Since appendix table is not given, from the F distribution table, with 3 degrees of freedom for the numerator and 22 for the denominator, the critical value is, F0.05 = 3.0491 [or using the Excel function, =F.INV(0.95,3,22)] c) Test statistic: The F test statistic value is as follows: (d) Calculate R2 and R2adj.

Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
