Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than ...

Imagine 1,000 coin flips, and the distribution approaches the normal bell curve. A probability density function (PDF) explains which values are likely to appear in a data-generating process at any ...

This video describes the central limit theorem and some properties of the normal distribution. Understanding this will help you tie together many of the different types of hypothesis tests and ...
