This statistics video tutorial provides a basic introduction into standard normal distributions. It explains how to find the Zscore 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 Ztables. This video contains plenty of examples and practice problems.
