D)F-ratio.

Question

Quizplus · Accepted Answer

The standard error of estimate measures the vertical spread of the data points about the regression line, indicating the average amount of variation between the observed values and the predicted values by the regression equation. The regression coefficient is a measure of the strength and direction of the linear relationship between the variables, and it does not provide information about the spread of the data. The y-intercept is the value of the response variable when the predictor variable is equal to zero, and it also does not indicate the spread of the data. The F-ratio is used in hypothesis testing to determine the significance of the regression model, and it does not measure the spread of the data.
