Question

you use a line of best fit for a set or data to make a prediction about and unknown value. the correlation coefficient for your data set is 0.019. how confident can you be that your predicted value will be reasonably close to the actual value?

Answer 1

A correlation coefficient of 0.019 indicates a very weak or almost non-existent linear relationship between the variables. Therefore, using a line of best fit to make predictions based on this data set may not be very accurate.

In such a scenario, it would be challenging to have confidence in the accuracy of the predicted value. It is recommended to use caution when making predictions based on a weak correlation coefficient since the predicted value may be far from the actual value.
