True or False 1 The magnitude of the correlation indicates t

True or False.

1. The magnitude of the correlation indicates the direction of the relationship.

2. A correlation of 1 indicates no relationship between two variables.

3. The SP can never be negative.

4. A correlation of -.4 between income and a measure of health (higher numbers indicating better health) indicates that wealth causes poor health.

5. The correlation is similar to the regression coefficient except that the correlation is standardized.

6. A correlation of 0 indicates a positive relationship between two variables.

Solution

1.False, it indicates The magnitude of r (how far away from zero it is) indicates the strength of the relationship.

2. False it indicates that there is a strong linear relationship between the variables

3.What is SP?

4.False, correlation coefficient always lies between -1nd 1

5.False, The correlation coefficient is a measure of linear association between two variables where as regression analysis is a statistical process for estimating the relationships among variables

6.False, The weakest linear relationship is indicated by a correlation coefficient equal to 0
