6. Vocabulary Binomial Distribution: specifies the number of times (x) that an event occurs in n Bernoulli trials where p is the probability of the event occurring in a single trial. Normal Distribution: are a family of distributions with a symmetrical bell shape Bernoulli Trials: is an experiment where there are only two possibly outcomes (ie. true or false) and each experiment is independent and the outcome is exclusive that trial. Central Limit Theorem: The distribution of an average tends to be Normal, even when the distribution from which the average is computed is decidedly non-Normal (3).
