Statistics 2nd Grading Period Power Objectives: Academic Vocabulary: Calculate expected values and use them to solve problems. (P.O. #8) Use probability to evaluate outcomes of decisions. (P.O. #9) random variable probability distribution discrete random variable continuous random variable expected value binomial distribution Poisson distribution geometric distribution Probability Distributions Enduring Understandings: Essential Questions: A probability distribution is just a range of expected values from a situation or event that has outcomes involved. Binomial, Poisson, and geometric distributions are normal occurrences in nature and we can calculate the probability of these events happening. Expected value is a prediction of what may happen and can help you to make intelligent decisions in life events of finances, medical and relational events. Why is it important and intriguing to know the probability of an occurrence? In what ways is a binomial distribution different that a probability distribution and how can knowing how to find the probability of these help is predict future events? The special probability distributions of Poisson and geometric help us make predictions of natural occurrences such as hurricanes and earthquakes. Why is this important for us to know and how can we use this knowledge to protect and improve our world? What is an expected value and how do I use this knowledge to make informed decisions?
