Question

fill in the blanks so the resulting statement is true. a measure that is used to describe the strength and direction of a relationship between variables whose data points lie on or near a line is called the ____, ranging from ( r = )__ to ( r = )____. a measure that is used to describe the strength and direction of a relationship between variables whose data points lie on or near a line is called the regression coefficient, causation coefficient, regression line, correlation coefficient, ranging from ( r = ) to ( r = )

Explanation:

The correlation coefficient \( r \) measures the strength and direction of a linear relationship between variables. Its value ranges from \( r=-1 \) (perfect negative linear relationship) to \( r = 1 \) (perfect positive linear relationship). The regression coefficient is related to the slope of the regression line, causation coefficient is not a standard statistical term in this context, and the regression line is a line of best - fit, not a measure of strength and direction like \( r \).

Answer:

correlation coefficient, \( r=-1 \), \( r = 1 \)
