Question

(CO 6) If the linear correlation coefficient is -0.491, what is the

Answer 1

The value of co-efficient of determination is 0.241.

What is the relationship between linear co-relation co-efficient and co-efficient of determination ?

The co-efficient of determination R² is similar to the linear correlation co-efficient.

We can think of co-relation of determination as a percentage. It gives us the data for how much percentage of data will fall within the linear co-relation.The higher the percentage the more data falls within.If the coefficient is 0.5 then 50% of data falls within the linear co-relation.

According to the given question

Linear correlation coefficient is -0.491

∴ Co-efficient of determination is (-.491)² which is equal to 0.241.
