Statistics 101: Introduction to the Poisson Distribution In this video we discuss the basic characteristics of the Poisson Distribution using a real-world example involving a checkout line at a supermarket. Having a basic understanding of the binomial distribution is helpful, but not necessary. I also show you how to calculate Poisson probabilities on at TI […]

Statistics 101: The Binomial Distribution. In this video we learn the basics of the binomial distribution using the simple sales performance data of two salespersons. Given a fixed success rate and call volume, what is the probability of closing a certain number of sales per day? We use our knowledge of basic discrete probability distributions, […]

An introduction to the binomial distribution. I discuss the conditions required for a random variable to have a binomial distribution, discuss the binomial probability mass function and the mean and variance, and look at two examples involving probability calculations. The estimated probability of a 90 year old Canadian male surviving for one year was taken […]

I 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 […]
