Introduction to The Chi-Square Distribution | Introduction ... This distribution is called the chi-square distribution. In this chapter, you will learn the three major applications of the chi-square distribution: the goodness-of-fit test, which determines if data fit a particular distribution, such as in the lottery example TI-83+ and TI-84 calculator instructions are included in the text. Hints for Statistics Using a TI-83 Hints for Statistics Using a TI-83. Chi-square and F distributions are restricted to nonnegative values, so that you can enter 0 The TI-83 may take up to 30 seconds to find the solution, which is a long time if you are looking at the TI-83 patiently waiting for your answer. You can tell that the TI-83 is still thinking since there will Notes on the Chi-Squared Distribution - People Notes on the Chi-Squared Distribution October 19, 2005 1 Introduction Recall the de nition of the chi-squared random variable with k degrees of freedom is given as ˜2 = X2 1 + +X2 k; where the Xi’s are all independent and have N(0;1)distributions. Also recall that I claimed that ˜2 has a gamma distribution with parameters r = k=2 and = 1=2
