Archetype Definition: a common character, image, symbol, or situation that occurs in literature and in life, and considered to be universal across most cultures. Archetype examples are found in the world around us every day: in our speech, our beliefs, media, sports, video games, psychology, art, and even our dreams. Archetypes are universal; that is, they occur across all cultures, religions, and parts of history.
The above plot illustrates Poisson probabilities for Î» = 7.5. and this plot illustrates Poisson probabilities for Î» = 15. The mean of the Poisson distribution is Î». For the Poisson distribution, the variance, Î», is the same as the mean, so the standard deviation is âÎ». Empirical tests. There are also some empirical ways of checking for a Poisson distribution. 1  The simplest and handiest way is to see if the variance is roughly equal to the mean for your Poisson data.
The second objective is to meas-ure the Youngâs Modulus and Poissonâs Ratio using quasi-static methods. The third objective is to compare the quasi-static and dynamic results. The dynamic results are based on the assump-tion that Poissonâs Ratio is invariant and can be measured using the quasi-static procedures.
