https://youtu.be/tDLcBrLzBosI describe the standard normal distribution and its properties with respect to the percentage of observations within each standard deviation. I also make reference to two key statistical demarcation points (i.e., 1.96 and 2.58) and their relationship to the normal distribution. Finally, I mention two tests that can be used to test normal distributions for statistical significance.
normal distribution, normal probability distribution, standard normal distribution, normal distribution curve, bell shaped curve
