Notes on the Chi-Squared Distribution October 19, 2005 1 Introduction let us now use it to determine the moment generating function for the chi-square distribution; rst, we determine the m.g.f. for a gamma distribution: After doing a table lookup, it turns out that P

These tables are designed to be complete enough and easy to use for exams. Standard normal table of left tail probabilities. H or H the alternative hypothesis. O observed count. E expected count. 2 test χ critical chi-square test value. 2 table χ chi-square value from the table. Formulae. For that reason, we'll now explore how to use a typical chi-square table to look up chi-square values and/or chi-square probabilities. Let's start with two The Chi-Square ( X2) Statistic. ▫ Categorical data may be displayed in contingency tables. ▫ The chi-square statistic compares the observed count in each table
Both use the chi-square tables. Expected counts should be greater than 5 for the table to give a good approximation. Goodness of fit: are the counts consistent
The minimum expected count is 10.00. Results: From the top row of the last table, Pearson Chi-Square statistic, χ2 = 71.20, and p < 594 Tables. I'.

For exam ple, the goodness -of-fit Chi-square may be used to test whether a set of values follow the normal distribution or whether the proportions of Democrats, Republicans, and other parties are equal to a certain set of values, say 0.4, 0.4, and 0.2.
