Standard Normal Distribution Tables, Z Scores, Probability & Empirical Rule – Stats

3.2M views on YouTube

This statistics video tutorial provides a basic introduction into standard normal distributions. It explains how to find the Z-score given a value of x as well as the mean and standard deviation. It explains how to determine the probability by finding the area under the curve represented by f(x) – the probability density function using the empirical rule and the Z-tables. This video contains plenty of examples and practice problems.
