Question

e the value of the linear correlation coefficient to calculate the coefficient of determination. What does this tell you about the explained variation of the data about the negression line? About the urexpiained variation? -0.193 alculate the coefficient of determination. Round to three decimal places as needed.) What does this tell you about the explained variation of the data about the regression line? % of the variation can be explained by the regression line. Round to one decimal place as needed.) About the unexplained variation? %ofthe variation is unexplained and is due to other factors or to sampling emor (Round to one decimal place as needed.) Enter your answer in each of the answer boxes

Explanation / Answer

Ans:

a)cofficient of determination=r^2=0.193^2=0.037

b)Percentage of Explained variation=3.7%

c)Percentage of Unexplained variation,1-r^2=1-0.037=0.963 or 96.3%
