How to Calculate the Appropriate Test Statistic and p-Value for the Chi-Square Test for Goodness of Fit Step 1Identify the sample size {eq}n {/eq} and the categories of the random variables by {eq}1,2,3,..,k {/eq}. Set the null hypothesis ...
If the p value is less than the significance (e.g., a=0.05), we can reject the null hypothesis that views are independent of gender. Gender and point of view are related; men and women have different points of view. QI Macros also containsChi Square Goodness of Fit TestsandFisher Exact...
Both use the chi-square statistic and distribution for different purposes: A chi-square goodness of fit test determines if sample data matches a population. For more details on this type, see: Goodness of Fit Test. A chi-square test for independence compares two variables in a contingency ...
This lesson describes when and how to conduct a chi-square goodness of fit test. Key points are illustrated by a sample problem with solution.
