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,...
Chi-Square/Contingency Table Analysis
Professor Johnson who is a professor at Yale’s University and
wanted to see if his grade distribution after his first year of
teaching was comparable to the overall university grade
distribution, which has the following percentages: A = 10%, B =
22%. C = 40%, D = 21% and F = 7%. The distribution of Professor
Johnson grades for 323 students at the end of his year was a
follow: 38 students received As, 78 received Bs,...
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
In Chi-square goodness of fit and contingency table tests, it is
sometimes necessary to reduce the number of classifications used in
order to do what? Explain why.
Statistics
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....
