WebJul 14, 2024 · The basic trick that a goodness of fit test uses is to construct a test statistic that measures how “close” the data are to the null hypothesis. If the data don’t resemble what you’d “expect” to see if the null hypothesis were true, then it probably isn’t true. Okay, if the null hypothesis were true, what would we expect to see?

WebMar 5, 2016 · An attractive feature of this test is that the distribution of the K-S test statistic itself does not depend on the underlying cumulative distribution function being tested. Another advantage is that it is an exact test (the chi-square goodness-of-fit test depends on an adequate sample size for the approximations to be valid). WebA chi-square goodness of fit test is used to test whether a 0-9 spinner is "fair" (i.e., the outcomes are all equally likely). The spinner is spun 100 times, and the results are recorded. hi fi rush thumbnail
