In this statistics video tutorial you will learn how to build a Confidence Interval, and more importantly, how the concept of the Sampling Distribution of the Mean is used to construct the confidence interval.
This video focuses on the concepts and principles that a confidence interval is based on, with following videos focussing more on the calculation, interpretation, and other finer details of constructing confidence intervals.

We present the concept in reference to a 95% confidence interval for the population mean, although we also discuss how this can be generalized for different levels of confidence, as well as what the 95% confidence interval meaning and interpretations are.

This video will also help to answer commonly asked questions like what is the difference between confidence interval vs confidence level? Why do we use a t distribution?

The goal for this video is to use the understanding of confidence interval built up here as a foundation for understanding the general principal that all confidence intervals are based on. By building an understanding of how close/far estimates like the sample mean tend to be from the true value/population mean, we will also know how close/far the true value/population mean tends to be from the sample mean.
