The Normal Distribution and the 68-95-99.7 Rule
The Normal Distribution and the 68-95-99.7 Rule. In this video, I talk about the normal distribution and what percentage of observed values fall within either 1, 2, or 3 standard deviations from the mean. One specific example is discussed. For more free math video, visit PatrickJMT.com

Mean and Variance of Normal Distribution
Calculus/Probability: We calculate the mean and variance for normal distributions. We also verify the probability density function property using the assumption that the improper integral of exp(-x^2) over the real line equals sqrt(pi).
