How to determine independence in probability
WebDec 7, 2024 · To determine whether two events are independent or dependent, it is important to ask whether the outcome of one event would have an impact on the outcome of the other event. If the outcome of one event does not affect the outcome of the other event, the events are independent. WebTests of independence involve using a contingency table of observed (data) values. The test statistic for a test of independence is similar to that of a goodness-of-fit test: Σ ( i ⋅ j) ( O – E) 2 E where: O = observed values E = expected values i = the number of rows in the table j = the number of columns in the table
