Using only a point estimate can be associated with low certainty, as there may be variation in the sample data. The interval estimate gives researchers a higher level of confidence by providing a range of values that is likely to contain the true population parameter. Therefore, using an interval estimate can add certainty to the estimate of the population mean.
