Confidence and prediction bands are often used as part of the graphical presentation of results of a regression analysis. Confidence bands are closely related to confidence intervals , which represent the uncertainty in an estimate of a single numerical value.... The first chart (see below) allows us to visualize the data, the regression line (the fitted model), and two confidence intervals: the confidence interval on mean of the prediction for a given value of the Height is the one closer to the line.

Statistics- Prediction Interval? Excel Tips & Solutions

Prediction intervals will be computed for you when using any of the benchmark forecasting methods. For example, here is the output when using the naïve method for the Google stock price. For example, here is the output when using the naïve method for the Google stock price....
We call this a prediction interval for individual responses, to distinguish from the confidence interval for mean response. As usual, there is more variation in individual responses than there is in means, so the prediction interval is wider than the confidence interval. But the formula is strikingly similar to the
