Chi Square? Outline the basic ideas behind the chi-square test of independence. What null and alternative hypotheses are used? How does a chi-square test of homogeneity differ from a chi-square test of independence? Describe a Goodness of Fit Test. What are the cells? How many degrees of freedom are there

In a research article, the authors said that they used a chi-square test for independence for testing whether there is statistically significant correlation between two categorical variables. Each of categorical variables has two categories of outcomes. So, the contingency table for crossclassifying these two variables is a 2x2 table. They reported the chi-square statstic value for this test of independence and it is 5.21. Please mark all statements that are correct. A The correlation between the two categorical variables is...

The Chi-Square test of independence is used to determine if there is a significant relationship between two nominal categorical variables. The frequency of one nominal variable is compared with different values of the second nominal variable. The chi-squared goodness of fit test is appropriate when the following conditions are met: The sampling method is simple random sampling The variable under study is categorical The expected value of the number of sample observations in each level of the variable is at...
