Note: Your teacher will grade your responses to the follow questions to ensure you receive proper credit for your answers.
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 Negative 0 point 833. Can you be confident that your predicted value will be reasonably close to the actual value? Why or why not?
(2 points)
No, you cannot be confident that your predicted value will be reasonably close to the actual value. A correlation coefficient of negative 0.833 indicates a strong negative linear relationship between the variables. However, it does not imply the accuracy or precision of the predicted value. The closeness of the predicted value to the actual value depends on other factors such as the spread of the data points around the line of best fit and the presence of outliers.
