Using only a point estimate can be associated with low certainty as it provides only one value as an estimate of the parameter. The interval estimate provides a range within which the parameter is likely to fall, increasing the level of confidence researchers have in the estimate. Therefore, using both a point estimate and an interval estimate can help to add certainty to the estimate of the population mean.
