Interpreting a confidence interval: Homework; A point estimator is just the statistic that you have calculated previously. As an example, when you wanted to estimate the population mean, $\mu$, the point estimator is the sample mean, $\overline{x}$.

Confidence Intervals. In statistical inference, one wishes to estimate population parametersusing observed sample data. A confidence intervalgives an estimated range of values which is likely to include an unknown population parameter, the estimated range being calculated from a given set of sample data.

What is a Confidence Interval? Confidence intervals are an essential part of inferential statistics, upon which most market research is based. Put simply, in statistics, a confidence interval is a type of interval estimate that is computed from the data that has been observed from a sample. After we build a confidence interval for a mean, it's important to be able to interpret what the interval tells us about the population and what it doesn't tell us.
