Question

- What is precisely the difference in the situation for independent samples and matched paired samples t-test that lead to different types of computation of t-values.

Answer #1

Question:
Please indicate if the following are independent or paired samples
of t-tests:
a) Attitudes of 8th graders toward art before and after visiting a
museum on a field trip
b) Differences in political opinions of father and sons
c) Differences in rates of attendance at Rutgers football games for
students raised in New Jersey and those raised
in Pennsylvania
d) Differences between freshman and sophomores in the class on time
spent studying
e) A comparison between education levels of the...

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.

What is the difference about n in a independent t-test and a
matched pair at-test

What is the difference between a t test for independent
samples and a t test for related (dependent) samples?
Give an example of when you would use each?

What happens if you take independent samples test instead of
paired test?

The test is: Conduct a two-independent samples t test to
determine if people with high IQs differ reading level compared to
people without a high IQ.
Using this table, first state if this test is directional or non
directional. write the test results for a two-independent samples
t-test. State which value...

When we compute an independent-samples t-test, we are
looking to see if there are significant differences between the
means of two independent groups, each measured on a different level
of the independent variable.
True or False
When we compute a paired-samples t-test, we are looking
to see if there are significant differences between the means of
two independent groups, each measured on a different level of the
independent variable.
True or False
If the p-value is > than 0.05, the...

What is the difference between a One sample
t-test, Unpooled t-test, Pooled
t-test, Paired t-test, and Mann
Whitney U test? How do you know when to use each test?

a) Provide a real life example scenario for a paired-samples
t-test that includes sample data for N = 4 in each
condition. Do not only present the numbers; you need a reasonable
example of something that could be tested with a paired-samples
t-test.
b) Explain why your example is appropriate for a paired-samples
t-test.
c) Conduct the paired-samples t-test (two-tailed test
with an alpha of .05), showing your work for each step.

For this week's assignment, find an article that uses either an
independent samples t-test or a correlated (also known as "paired")
t-test. 1. Give me the APA reference for it. 2. What is the article
about? 3. What did the article discover?
