Question

Does the correlation coefficient r = 0.998762 show a decrease or increase from left to right on a coordinate plane with the line of best fit

Answer 1

A correlation coefficient (\( r \)) of 0.998762 indicates a very strong positive linear relationship between the two variables being analyzed. This means that as one variable increases, the other variable also tends to increase. Therefore, on a coordinate plane with the line of best fit, you would see an increase from left to right. In summary, a correlation coefficient close to 1 (like 0.998762) indicates a steep upward slope of the line of best fit, showing a clear increase.
