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

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

For each of the following examples, state whether the chi-square
goodness-of-fit test or the chi-square test for independence is
appropriate, and state the degrees of freedom (df) for the
test.
Part A) An instructor tests whether class attendance (low, high)
and grade point average (low, average, high) are independent.
- State whether the chi-square goodness-of-fit test or the
chi-square test for independence is appropriate.
- State the degrees of freedom for the test. df =

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.

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...
