Question 7 The standard error of estimate could be thought of as the: A standard deviation of the data points around the regression line. B standard deviation of the independent variable. C standard deviation of the dependent variable. D amount of error made in a random selection. Question 8 Which statement about the slope of the simple linear regression line is true? A It has the same sign as the correlation. B It is expressed as a standardized value. C The square of the slope is the proportion of variation in Y explained by X. D It is the value of Y when X is zero.

Which of the following is true for regression analysis? When the actual values of the dependent variable and the corresponding predicted values are the same, the standard error of estimate will be zero. The vertical spread of the data points about the regression line is measured by the y-intercept. If the coefficient of determination is [missing value], then the coefficient of correlation must be [missing value]. None of the suggested answers are correct. The vertical spread of the data points about the regression line is measured by the change in the slope.

The _________________ tells us how much of the percentage change in the dependent variable (Y) is explained by the percentage change in the independent variable (X) for a causal forecasting model. standard error correlation coefficient coefficient of determination slope of the regression line
