What is the appropriate test (e.g., Independent Samples T Test,
Paired Samples T-Test, ANOVA, Correlation) and why (e.g., what type
of variables are you analyzing)?
What is the effect of living arrangements on the overall
satisfaction at University.

discuss the differences between a one-sample z-test, one-sample
t-test, the independent samples t-test and the dependent samples
t-test. Specifically, under what circumstances would you conduct
each test and what type of information comes from a known/defined
population versus your sample data?
An independent-samples t test is performed on the
samples below:
Sample 1: M = 24.1, s2...
An independent-samples t test is performed on the
samples below:
Sample 1: M = 24.1, s2 = 32.02,
n = 10
Sample 2: M = 19.4, s2 = 44.46,
n = 10
a.)Calculate the standard error for the t test
(sM1-M2). (Round to 4 decimal
places.)
b.)Calculate the degrees of freedom for the t test.
c.)Find the critical value of t with two tails and
alpha = 0.05. (Keep 3 decimal places.)
d.)Calculate the t test. (Round answer to two decimal
places.)

samples, 1-way ANOVA
Researchers wanted to explore different treatment methods to
effect memory skills in high school freshmen. Subjects were given a
memory test (under multiple conditions) these were the results:

Political bias in academia and a paired-samples
t test: The following is an excerpt from the
abstract (brief opening summary) from a published research study
that examined a reported bias against conservatives in American
academia (Fosse, Gross, & Ma, 2011).
The American professoriate contains a disproportionate number
of people with liberal political views. Is this because of
political bias or discrimination?…We sent two emails to directors
of graduate study in the leading American departments of sociology,
political science, economics, history,...
