Normal distribution's probability density function derived in 5min

Order: Reorder
Duration: 4:50
Updated: 22 Aug 2013

The proof comes from Grossman, Stanley, I., Multivariable Calculus, Linear Algebra, and Differential Equations, 2nd., Academic Press, 1986., and Hamming, Richard, W. The Art of Probability for Engineers and Scientists, Addison-Wesley, 1991. This was summarized by Dan Teague of the North Carolina School of Science and Mathematics. This did not use characteristic functions or moment generating function to derive, because this explanation was straightforward. A disclaimer is that, in the second step, the improper integral appears without proper treatment that this is allowed. However, digging into the details of this would be beyond the scope for this video made to make the content simple.

ProbStats8: The normal distribution

Order: Reorder
Duration: 48:24
Updated: 28 Nov 2013

In this final lecture in this short introduction to Probability and Statistics, we introduce perhaps the most important probability distibution: the normal distribution, also known as the `bell-curve'. Its role is clarified by the Central Limit theorem, a key result in Statistics, that states roughly that if you sample an arbitrary probability distribution, discrete or continuous, then the averages of that sample end up resembling more and more a normal distribution as the number of terms in the sample increases. Here we start with the standard normal, which has mean 0 and variance 1. Although we cannot compute probabilities directly with it, in the sense of evaluating integrals precisely, we can do so approximately. The Cumulative distribution function is a useful tool in helping us do this--essentially just the integral of the probability density function. A general normal distribution is related to a standard normal via an affine transformation, and I explain how to go from one to another: the idea being that questions about a general normal distribution are usually converted to standard normal questions, and the answers converted back. Thanks for watching the series!
