median vs IQR skewed data uses these for center and spread Histogram - when to use Based on the shape of the distribution, uses mean + standard deviation OR median + IQR to describe center and spread - Larger data sets; shows shapes of distribution and potential outliers; ignores the individual data valuesl Histogram Skewed right Not a symmetric distribution, the tail is on the right Standard Deviation Rule 68% of the data are within 1 standard deviation, 95% are...

WGU Statistics Questions and Answers Already Passed The probability of any event is between one and o. What is the equation for this? For any event A, 0 ≤ P(A) ≤ 1. The sum of all possible probabilities is___? One, the equation is :P(S) = 1 What is the complement rule? or the probability that an event does not occur is 1 minus the probability that it does occur. P(not A) = 1 - P(A) In probability, "OR" means either one or the other or both. P(A or B) = P(event A occurs or event B occurs...
