A confidence interval would be useful to researchers interested in aggregate data.
This interval will contain the true population mean for a polysomnography parameter measured in healthy adults with 95% probability.
|
A Prediction Interval would be useful to clinicians assessing individual polysomnography parameters.
This interval is always wider than a confidence interval and will contain an individual value for a polysomnography parameter measured in a healthy adult with 95% probability.
