Hello students, in this question we have given the model summary and the anova table for the regression and by using that we have to solve the following questions.
00:10
Now in the first question, we have to explain what r signifies in the model summary.
00:16
So now capital r signifies signifies the multiple correlation coefficient, the multiple correlation coefficient and in the simple linear regression in the simple linear regression correlation coefficient correlation coefficient that is r signifies signifies the measure of the relationship the measure of the relationship relationship between the independent variable that is x and the dependent variable y.
01:24
However, a multiple correlation coefficient gives us the measure of the strength of the relationship between the observed values and the best predicted values of the dependent variable of y.
01:36
Therefore here r signifies the correlation between the observed values of attitude and the best predicted value of attitude which is predicted using importance and duration as the predictors.
01:48
Then in the second question, we have to explain how do you explain r square in the model summary.
01:54
So now we know that r square tells us that the amount of variation in the dependent variable explained by the independent variable and here we have the value of r square is equal to 0 .945 which means that 94 % of the variability 94 % of the variability in the dependent variable that is in the attitude attitude is explained by is explained by the independent variables, which are importance by importance and the duration.
02:52
So this is the interpretation of the r square...
