If the coefficient of correlation is 0.65, the percentage of variation in the dependent variable explained by the estimated regression equation is a. |
0.65% |
b. |
80% |
c. |
0.42% |
d. |
42.2% |
Coefficient of correlation, r = 0.65
Coefficient of determination, r2 = 0.652 = 0.4225
Percentage of variation in the dependent variable explained by the estimated regression equation = 0.4225 x 100
= 42.25%
Ans: d. 42.2%

If the coefficient of correlation is 0.8, the percentage of variation in the dependent variable explained by the estimated regression equation is a. 0.80% b. 80% c. 0.64% d. 64%
The proportion of the variation in the dependent variable y that is explained by the estimated regression equation is measured by the _____. a. correlation coefficient b. coefficient of determination c. confidence interval estimate d. standard error of t
True or False: The correlation coefficient is the ratio of explained variation to total variation.
The correlation coefficient is a summary measure that Select one: a. is of limited use because it fails to indicate the direction of the relationship between the variables. b. indicates the change in Y for a one unit change in X. c. indicates the strength of linear relationship between a pair of quantitative variables. d. indicates the proportion of variation in Y that is explained by the variation in X. e. none of the above. In regression analysis, the F...
If the cost equation yields a coefficient of determination of 77%, it means that the: a. dependent variable explains 23% of the variability in cost. b. dependent variable explains 77% of the variability in cost. c. independent variable explants 23% of the variability in cost. d. independent variable explains 77% of the variability in cost. The percentage of variability in the dependent variable explained by an independent variable is called the: a. coefficient of correlation. b. coefficient of regression. C....
Finding Measures of variation. In Exercises find the (a) explained variation (b) unexplained variation, (c) total variation, (d) coefficient of determination, and (e) standard error of estimate se. In each case, there is a significant linear correlation so that it is reasonable to use the regression equation when making predictions.Cholesterol and BMI Refer to the paired cholesterol/BMI data for women as listed in Data Set 1 in Appendix B. (Let x represent the cholesterol levels.)
The multiple correlation of several variables with a dependent variable is a) less than the largest individual correlation. b) equal to the correlation of the dependent variable to the values predicted by the regression equation. c) noticeably less than the correlation of the dependent variable to the values predicted by the regression equation. d) It could take on any value
The correlation coefficient is: Multiple Choice the range of values over which the probability may be estimated based upon the regression equation results. the proportion of the total variance in the dependent variable explained by the independent variable. the measure of variabililty of the actual observations from the predicting (forecasting) equation line. the relative degree that changes in one variable can be used to estimate changes in another variable.
The coefficient of determination: Choose one • 10 points A. Represents the percentage of the data that can be explained by the correlation B. Is equal to the ratio of the explained variation to the total variation C. Is calculated by squaring the correlation coefficient. D. All of the above
