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 0.109. How confident can you be that you’re predicted value were reasonably close to the actual value.
1 answer
You cannot be very confident that your predicted value is reasonably close to the actual value since the correlation coefficient is so low. A correlation coefficient of 0.109 indicates that there is a very weak relationship between the two variables.
