Do all variables follow normal distribution? Explain why or why not. Explain with examples.

Jun 16th, 2015

Thank you for the opportunity to help you with your question!

variables that follow the normal distribution form a bell-shape curve called the Gaussian. Variables that do not follow the normal distribution tend to form a more different curve that varies significantly from the Gaussian, the curves of non-normal distributions include skew, kurtosis, etc.

examples of variables that do not form a normal distribution include the vertical height of male and female. When combined together, the distribution is binomial but turns to be normal distribution if heights are done in separate tests

Please let me know if you need any clarification. I'm always happy to answer your questions.
