By computing confidence intervals, a researcher can estimate how precise her research results are likely to be. Confidence intervals provide a range of values that is likely to contain the true population parameter with a specified level of confidence. Therefore, the narrower the confidence interval, the more precise the estimate. Confidence intervals do not necessarily address the problems of having a nonrepresentative sample or increase confidence in an estimate from a small sample.
