The variable about which the investigator wishes to make production on is called the ___. A. Department variable B. Unit of C. independent variable D. variable In regression analysis the quantity that gives the amount by which Y changes for a unit change in X is called the ___. A. Coefficient of determination B. Slope of the regression line C. Y intercept of the regression line D. Correlation coefficient In the equation of Y = b_e + b_ pi_ b_ is the ___. A. Coefficient of determination B. Slope of the regression line C. Y intercept of the regression line D. Correlation coefficient In the equation Y = b_ + b_ b_ is the ___. A. Coefficient of determination B. Slope of regression line C. Y intercept of the regression line D. Correlation coefficient In regression and correlation analysis the measure whose values are restricted to the range 0 to 1, inclusive, is the ___. A. Coefficient of determination B. Slope of the regression line C. Y intercept of the regression line D. Correlation coefficient In regression and correlation analysis the measure whose values are restricted to the -1 to +1, inclusive, is the ___. A. Coefficient of determination B. Slope of the regression line C. Y intercept of the regression line D. Correlation coefficientExplanation / Answer
20. Correct option
A: Dependent variable
REASON: The investigaor makes changes in the independent variable x in order to make predictions on dependent variable Y.
21. Correct option
B. Slope of the regression line.
REASON: In the regression line, suppose you make a unit change in x. Then the amount of change in Y is given by m, the slope.
22. Correct option:
C. Y intercept of the regression line.
REASON: Y intercept of the regression line is the value of Y at the point where the line crosses the y axis.
23. Correct option:
B. Slope of the regression line
REASON: In the egression line, m, the coefficient of x, is the slope.
24. Correct option:
A. Coefficient of determination.
REASON: The coefficient of determination = r2, where r is the coefficient of correlation. The coefficient of correlation varies between - 1 to 1, whereas the coefficient of determination varies between 0 to 1.
25. Correct option:
D. Correlation coefficient.
REASON: The coefficient of correlation varies between - 1 and + 1.
