Question

Quizplus · Accepted Answer

The prediction interval accounts for the uncertainty in predicting a single response value, while the confidence interval estimates the uncertainty around the mean response for given x-values. The key difference in their formulas is the addition of 1 to the quantity under the radical sign in the prediction interval formula, reflecting the extra variability associated with predicting a single response rather than the mean response.
