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 lease
Can you please provide an example of above --->. Do you have an example to share with us?

Chi-Square Test for Independence
Using Chi-Square, we are looking to see if there is a
significant difference between what we would expect results to be,
and what the actual results were. That is, expected vs.
observed. Use alpha = .05

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.

When we run a chi-square test of independence on a 2x2 table,
the resulting Chi-square test statistic would be equal to the
square of the Z-test statistic from the Z-test of two independent
proportions. True or false

You have been using the chi-square test of independence to test
for association between two variables.

expect to find no association.
2) Give an example of a pair of variables for which you would
expect to find association, but not a causal relationship.
3) Finally, give an example of a pair of variables for which you
would expect to find a causal relationship.
