10. Video: Traditional Confidence Intervals

One educated, but potentially biased opinion on the traditional methods is that these methods are no longer necessary with what is possible with statistics in modern computing, and these methods will become even less important with the future of computing. Therefore, memorizing these formulas to throw at a particular situation will be a glazed-over component of this class. However, there are resources below should you want to dive into a few of the hundreds if not thousands of hypothesis tests that are possible with traditional techniques.

To learn more about the traditional methods, see the documentation here on the Stat Trek site on the corresponding hypothesis tests. In the left margin of this Stat Trek page, you will see a drop-down list of the hypothesis tests available, as shown in the image below.

Each of these hypothesis tests is linked to a corresponding confidence interval, but again the bootstrapping approach can be used in place of any of these! Simply by understanding what you would like to estimate, and simulating the sampling distribution for the statistic that best estimates that value.
