Z-Score CORRECT ANSWERS: Data points only. Measurement of a scores relationship to the mean. A statistical measure that indicates the number of standard deviations a data point is from its mean. Variance CORRECT ANSWERS: How far a set of numbers are spread. Used for Data set. Hint Words = Risk, spread. Multiplication Rule CORRECT ANSWERS: A method for finding the probability that both of two events occur. When the probabilities of multiple events are multiplied together to determine the likelihood of all of the events happening. Word Hint: And Addition Rule CORRECT ANSWERS: A method for finding the probability that either or both of two events occur. When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. Word Hint: Either/or.
