Question

Which of the following statement(s) is/are correct with respect to regression coefficients?

Statement 1: It measures the degree of linear relationship between two variables.

Statement 2: It gives the value by which one variable changes for a unit change in the other variable.

Which of the following is correct?

Options

• Statement 1 is true and statement 2 is false.

• Statement 2 is true and statement 1 is false.

• Both the statements are true.

• Both the statements are false.

Answer 1

Statement 2 is true and statement 1 is false.

Explanation:

Statement 1 is false because the strength of a linear relationship is measured by correlation (r), not regression. Statement 2 is true because the regression coefficient is the slope and shows the average change in one variable for a 1-unit change in the other.
