1. Compare and contrast the correlation and the chi-square test of independence. How are they similar and how are they different (i.e. when to use each) 2. Come up with two hypothetical examples demonstrating both strategies or come up with "real-world" applications of these strategies in your professional life (i.e. how could you apply these in your work).

Choose either the Chi Square Goodness of Fit test OR the Chi
Square Test for Independence. Give an example of a research
scenario that would use this test, including your hypothesis AND
what makes the test suitable for your variables chosen

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

Compare the chi-squared test for goodness of fit to the
chi-squared test for independence. Be sure to mention number of
samples and the number of levels of categories for your comparison.
Also provide the alternative hypothesis for both.

1. Chi-square Test of Independence
A political psychologist is interested in whether the community
a person lives in is related to that person's opinion on an
upcoming water conservation ballot initiative. The psychologist
surveys a random sample of 96 people by phone from three different
communities, with the results shown in the table below. At a 10%
significance level, is there evidence that opinion on the water
conservation ballot initiative depends on community membership?

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...
