Week #15 and Finals Week
 Here is the Final TakeHome Quizam. It
does not include any multiplechoice items and will therefore be worth less
points than most of the other quizams.
This is due on Friday, 5PM, of Finals Week. I prefer
that you place it in my mailbox in North Murray, but if you cannot make it to
campus, send a highquality image via email.
 Here is a video reviewing the
ChiSquare Test of Association.
 Review this video on the
ChiSquare GoodnessofFit Test.
Copy the worked problem from the video and turn in for
16 points. This is due on Friday, 5PM, of Finals Week. I prefer that you place
it in my mailbox in North Murray, but if you cannot make it to campus, send a
highquality image via email.

Week #14: April 24th
 Read this article on narcissism and be
prepared to take a short quiz on Thursday. Here are several questions to
consider while reading the article: How was the narcissism of the students who
were photographed measured? How many researchers in the lab rated each
photograph? How did the researchers rate the narcissism of the photographed
persons? What were the magnitudes of the correlation coefficients for the main
hypotheses of the study? How did the authors of the study describe their
findings regarding the accuracy of the raters (judges)?

Week #13: April 17th

Week #12: April 10th
 Here's today's lab assignment. Do take
note that for the hand computations you can use SPSS to obtain the descriptive
statistics table, and you do not have to compute every CI or pairwise
comparison.
 Here's
a
Youtube video working the same problem we covered in class. I cannot
remember the F_obs value for the pairwise comparison we conducted in class,
but I think it is different than what is on the video, which means there is a
minor computational error somewhere (unless my memory is off).
 Read this Wikipedia entry on the replication crisis:
https://en.wikipedia.org/wiki/Replication_crisis We will have
a short quiz over the reading on Tuesday, April 10th.
 This week we'll finish our coverage of onefactor betweensubjects ANOVA.

Week #11: April 3rd

Week #10: March 27th

Week #8: March 6th

Week #7: Feb. 27th
 Here's the link to the online calculator for computing p_obs for a ttest:
https://surfstat.anu.edu.au/surfstathome/tables/t.php You can also
obtain values for the zdistribution.
 No inperson class on Thursday, March 1st! I'll be at a
conference in Phoenix,
Arizona discussing why psychologists will not give up NHST...or even try
anything different. In other words, we'll be discussing why psychologists
cannot change their own demonstrably maladaptive behavior. In lieu of class,
watch this online "lecture" for the
Dependent Samples ttest we learned in class today (this video is from
years gone by, so ignore any semesterspecific statements in the video).
Copy the worked problem from the video and turn in for
point next Tuesday.
 Work this Dependent Samples ttest problem
by hand, and turn in your work for points on Tuesday of
next week.
 Here's the handout in case you missed
class today.

Week #6: Feb. 20th

Week #5: Feb. 16th
 Read pages 407411 (through Study #1) of this
article by Daryl Bem, a well known social psychologist. What is the study
about? What are the methods used? What are the pvalues for the main results?
Do you think Bem used p_crit of .05 or .01?
How large are the statistical effects using Cohen's Conventions (small,
medium, large)? Did Bem report any confidence intervals? What are some
of the individual difference variables he explored in the study? Be sure to
read any footnotes for this paper or any other you might encounter. We'll have a brief
5item quiz over this paper on Tuesday IN CLASS (not in the lab).
 Read James Alcock's
critique of Bem's first study (You can scroll down and focus just on Experiment #1).
 Watch this video reviewing the ztest for means.
This video is from a previous semester, so ignore any timesensitive
statements. The problem in the video is here with the
additional problem you need to complete and turn in on
Tuesday (Feb. 20th).
Copy the work (not the initial problem slide, but the hypotheses, zvalues,
ES, CI, etc.) from the video. Turn in what you copy to show you followed along
with the video. Turn in your newly worked example involving the longterm
alcoholics as well.

Week #4 lab (Feb. 6th)

Week #3 lab

Week #2 lab

 Welcome to Quantitative Methods in Psychology!
 Here's what you need for this class:
 A scientific calculator.
You don't need a fancy TI83 or similar calculator, although one of these
will be fine, but a simple calculator will do. Make sure that if you buy a
new, simple calculator for this course it is labeled as a "scientific
calculator." A scientific calculator will possess a variety of statistical
functions, such as the mean and standard deviation. You can purchase a
simple scientific calculator at WalMart, Walgreens, etc. for approximately 10
U.S. dollars.
