Whenever CI are reported, it is essential to focus on the reported confidence level. A basic rule to remember, the higher the confidence level is, the wider the interval would be. Based on the confidence level, a true population mean is likely covered by a range of values called confidence interval.

#CONFIDENCE INTERVAL RSTUDIO CODE#
The R code below creates a scatter plot with: Using a confidence interval when you should be using a prediction interval will greatly underestimate the uncertainty in a given predicted value (P. Generally, we are interested in specific individual predictions, so a prediction interval would be more appropriate. Which one should we use? The answer to this question depends on the context and the purpose of the analysis. Thus, a prediction interval will be generally much wider than a confidence interval for the same value. Prediction interval or confidence interval?Ī prediction interval reflects the uncertainty around a single value, while a confidence interval reflects the uncertainty around the mean prediction values.
