Use calculators, spreadsheets, and tables to estimate areas under the normal curve.
#Galton board diy how to
Can someone pls teach me how to answer this question 24.
Recognize that there are data sets for which such a procedure is not appropriate. When put on a calculator the answer is -1/2 but it doesn't explain how it got there and I can't think of a solution as to why the answer is -1/2.
HSS.ID.A.4 Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. HSS.ID.A.3 Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers). HSS.CP.B.9 Use permutations and combinations to compute probabilities of compound events and solve problems. HSS.CP.A.1 Describe events as subsets of a sample space (the set of outcomes) using characteristics (or categories) of the outcomes, or as unions, intersections, or complements of other events (“or,” “and,” “not”). (b) Develop a probability model (which may not be uniform) by observing frequencies in data generated from a chance process. A Galton Board, also called a quincunx or bean machine, yields a normal distribution in the bins below the pegs around which balls fall. (a) Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. If the agreement is not good, explain possible sources of the discrepancy. Compare probabilities from a model to observed frequencies. 7.SP.C.7 Develop a probability model and use it to find probabilities of events. 7.SP.C.6 Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event. Larger numbers indicate greater likelihood. 
Common Core Standards 7.SP.C.5 Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring.
