24. You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is -0.015. How confident can you be that your predicted value will be reasonably close to the actual value ?

I get 2 points for this essay. Please help me someone! I really don't know how to answer this!! :[

Answer 1

Well correlation can range from -1 to 1, with 0 being no correlation at all

so -.015 is very close to 0, you would be not confident at all. This means your prediction is no better than a random guessing.
