One of the coolest biology professors at MIT, Professor David E. Housman, explaining the Poisson distribution. From 7.27 Principles of Disease, Spring 2008. His description from the class website: “I thought you might like to hear a bit more about the Poisson distribution. It really is quite important in biology. I thought one way I could do this would be to make a little quick time video for you on this topic. So I did. Let me know if you are actually able to download it and view it.”

In this tutorial you are shown how to calculate the mean and standard deviation from a normal distribution using the following example. A high jumper knows from experience that she can clear a height of at least 1.78m once in 5 attempts. She also knows that she can clear a height of at least 1.65m on 7 out of 10 attempts. Find to 3 dp the mean and standard deviation of the heights the jumper can reach

High Quality Content by WIKIPEDIA articles! In queueing theory, a queueing model is used to approximate a real queueing situation or system, so the queueing behaviour can be analysed mathematically. Queueing models allow a number of useful steady state performance measures to be determined, including: * the average number in the queue, or the system, * the average time spent in the queue, or the system, * the statistical distribution of those numbers or… More >>

In this video, I briefly discuss a situation that can be modeled by a Poisson Distribution, give the formula, and do a simple example illustrating the Poisson Distribution. For more free math videos, visit JustMathTutoring.com

We show you through an example how to work out probabilities from a normal distribution. A battery has a lifetime which is normally distributed with a mean of 62 hours and a standard deviation of 3 hours. What is the probability of a battery lasting less than 68 hours?
