Describe the kind of data that are collected for an independent-measures t test and the hypotheses that the test evaluates. The key to helping formulate your explanation would be to include the assumptions of this statistical model, the type of sample used in this model, and a statement about the null hypothesis.

Describe the kind of data that are collected for an
independent-measures t test and the hypotheses that the test
evaluates. The key to helping formulate your explanation would be
to include the assumptions of this statistical model, the type of

hypothesis.
Describe what an independent-measures t-test is. Compare it to a real world example

12. Comparing ANOVA and the t test for an
independent-measures hypothesis test
Suzanne Zeedyk, a developmental psychologist at Dundee
University’s School of Psychology, conducted a pilot study in which
parents started a half-hour walk with their infants in a
parent-facing or an away-facing stroller and then switched to the
other type of stroller midway. Her results suggest that parents
talked less to the babies, the babies had higher heart rates, and
they were less likely to fall asleep in away-facing...

hypothesis. (c) State the assumptions. (d) State the formula for
the test statistic. (e) State the rejection rule with (How to
reject the null hypothesis) (f) Give an real life example of how we
can use the independent samples t-test for two means.

: Independent Samples t Test Criterion: Identify IV, DV, and
hypotheses and evaluate the null hypothesis for an independent
samples t test. Data:
Minutes of practice:
Group 1: 55, 44, 62, 30, 78, 50, 52.
Group 2: 31, 40, 53, 22, 41, 16, 33.
Complete the following:
a. Identify the IV and DV in the study.
b. State the null hypothesis and the directional (one-tailed)
alternative hypothesis.
c. Can you reject the null hypothesis at α = .05? Explain why...

What kind of data lend themselves to perform an analysis of
variance and/or an independent-samples t test? Given your
answer above, why should you use analysis of variance instead of
just using an independent-samples t test?

Problem #2
1) Conduct an independent-measures t-test using the following
data set:
Group 1: 12 10 15 12 4 16 6 10 8
Group 2: 8 5 9 0 6 5 0 1
-
2) Determine the critical values (for an alpha of .05) that you
should use to evaluate this t-score.
Please be clear with your steps on how you solved. How did you
get each number and whether or not the hypothesis is rejected.
