State the critical value of ?2 and determine the
appropriate conclusion for a chi-square test for
association using the given information.
a) ? = 0.025, Number of rows = 5, Number of columns = 5, ?2 =
31.1
b) ? = 0.10, Number of rows = 7, Number of columns = 6, ?2 =
40.3
Which of the following interpretations of a Chi-square test is
CORRECT? (you may use the table below as reference).
a. Assume that a Chi-square test was conducted to test the
goodness of fit to a 3:1 ratio and that a Chi-square value of 2.62
was obtained. The null hypothesis should be accepted.
b. With the test of a 3:1 ratio, there are two degrees of
freedom.
c. The larger the Chi-square value, the more likely your results
are real.
d....
Chi Square Test
We will now use Excel to run an example of a chi square test.
Chi square test is checking the independence of two variables. Our
example will test if taking hormonal pills and being overweight are
related. We will test the independence on 200 random patients.
Thus, N=200. They will be divided first into two groups, those who
take hormonal pills and those who do not. Second, they will be
divided into three groups based on weight,...
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
Describe, through an example or two, the use of a contingency
table analysis (Chi Square test) in a business research project.
What conclusion(s) could we draw from a Chi Square test?
