Please be sure to
create a cover page so I can keep track of who submitted the document J
·
Read each question
FULLY and CAREFULLY before answering.
·
Use your time well –
look over the exam before starting and develop a plan. If you are stuck on a problem, move on and
come back to it later.
·
If you are completely stuck on a problem that is
marked with an ***, you may ask me and I will indicate what the right steps are
to solve that part of the question. This
will allow you to proceed with subsequent questions that rely on these
steps. Obviously, you will not earn
credit for those points and you should use this option judiciously.
·
Be clear about what
you are doing. The more clearly and
explicitly your steps are indicated, the easier it will be for me to award
partial credit.
·
Be sure to refer to
Gravetter and Wallnau as this exam will cover material learned in both RSM701
and RSM801 (which use the same book).
·
You may also wish to refer
to Pace’s e-guide to SPSS as a refresher for how to conduct the tests (as well
as videos placed in the helpful resources folder in the classroom).
·
If you are confused
about a question, ask me. I may not be
able answer, but I may provide a useful clarification. It doesn’t hurt to ask.

IF YOU DO AN
ANOVA, BE SURE TO CONDUCT AND REPORT A TUKEY POST-HOC TEST.
Instructions
Open “Final Exam Data” data in SPSS.
About these data:
Roy Baumeister and his colleagues study self-regulation. In other words, they
ask why don't we eat all of the tasty tidbits we encounter, attend parties when
we should be studying, and have sex with every attractive potential partner who
crosses our path? In short, how do we
manage to forgo temptation? An exploration of (fictitious) data regarding these
questions will comprise the bulk of the final lab exam.
The data set you opened represents scores of 800 recent college graduates
who participated in a study. First,
participants were asked to control their emotions while watching a very sad
movie, and then completed challenging set of brain teasers. One week later, participants returned to the
lab and again watched a sad movie. This
time, they were not asked to control their emotions and completed a different
(but equally challenging) set of brain teasers.
In both cases, the researchers measured how much participants persisted
at the difficult brain teasers. The variables in this data set are:
|
SUBJECT |
Unique subject identifier
from 1-800 |
|
PERSONALITY |
Personality Type (0 = Introvert;
1 = Extrovert) |
|
CTRL_PER |
Persistence after watching a
sad movie and being asked to control emotions (1-10 scale; higher numbers
indicate greater persistence). |
|
NO_CTRL_PER |
Persistence after watching a
sad movie and NOT being asked to control emotions (1-10 scale;
higher numbers indicate greater persistence). |
|
NEED_CTRL |
Self-report of need for
control in the environment, measured two months before participating in the
study (1-5 scale; higher numbers indicate greater need for control over one's
environment) |
|
JOB |
First job or activity
following college graduation (0 = Public service job; 1 = Graduate school; 2
= Travel; 3 = Private sector job) |
- Create
a new variable that represents the z-score of persistence on the brain
teasers after being asked to control emotions (CTRL_PER).
2 points SAVE FILE AS “LASTNAME.SAV” (SPSS WILL AUTOMATICALLY ADD THE .SAV
EXTENSION TO DATA FILES). BE SURE TO ATTACH THIS FILE TO BLACKBOARD
- Analyze
whether persistence on the brain teasers after being asked to
control emotions contains any outliers. Write up your conclusion (using
stats and a figure to back up your conclusions). Report what you
would do if you do find any outliers (delete, remove, transform), but
leave the variable as is. 4 points
- Is self-reported need
to control one’s environment associated with persistence scores
when participants did not control their emotions after watching a sad move
(variable NO_CTRL_PER)? The following questions are worth a
total of 8 points.
A.
What is the
appropriate test to conduct to answer this question?
B.
Conduct the
appropriate test to answer this question.
