Required Materials:
Aron, Aron, & Coups (2004). Statistics for the behavioral and social sciences. A brief course.
(3^{rd} ed.). Prentice Hall.
Nolan (2004). Study
guide and computer workbook. Prentice Hall.
You will also need a basic calculator.
Course content:
This course is an introduction to how social scientists
organize and interpret data.
Descriptive and inferential statistics will be covered.
Unlike most of your other classes, this is a “how to”
class. You will learn how to organize
statistical information in a meaningful way, how to use statistics to test
hypotheses, and how to interpret the outcomes of statistical tests. Furthermore, you will learn how to compute
some of today’s most commonly used statistics with a calculator and with
computerized statistical software. More importantly, you will learn how to
explain statistical information to others.
Course format: Homework will be assigned for each class. Class time
will be devoted to lecture, going over the homework problems, demonstrations,
inclass exercises, and computer lab work.
Why are you here?

How to figure out your grade:
Average of 4 exam scores ____________
X .80 = ____________
Homework grade ____________
X .20 = ____________
Total
= ____________ (Final grade)
About the Exams:
The midterm exams will test
you on material covered since the previous exam. However, the exams are
naturally cumulative because new material builds on preceding concepts.
Therefore, it is essential that you keep up with the material. If you do poorly
on an exam, it is important to review the relevant chapters in the book and
complete practice problems until you have mastered the material.
Exams 1 and 3 include
takehome sections that will be handed out in class 1 week before the inclass
exam and collected at the beginning of the inclass exam.
The final exam covers the new
material introduced after Exam 3 and cumulative material from throughout the
entire course.
To take the exams you must
arrive before the first person to finish leaves the room. Makeup exams will only be given for
students with University approved excuses (e.g., athletic participation,
illness, death of family member) and proof thereof.
About the Homework:
Homework assignments should
be completed prior to the start of each class.
Assignments must be written
neatly and show all work. Pencil or pen is fine.
I will collect homework at
the beginning of class on randomly selected days throughout the semester.
One and only one late
assignment will be allowed as long as the assignment is handed in by the start
of the next class.
Collected homework will be
graded on a 02 scale. 0 means the homework was not handed in, 1 means the
homework was incomplete or poorly done, 2 means the homework was done at a satisfactory
level.
Knowledge of mathematics:
The emphasis in this course
is on understanding the logic of statistics. However, understanding statistics
involves learning how statistics are calculated. The calculations require
nothing more than elementary highschool algebra.
Calculators:
You are encouraged to use a
calculator for doing assignments and completing exams. A simple, inexpensive
calculator that adds, subtracts, multiplies, divides, and takes square roots is
all you need. Since you must show all your work on all assignments and exams,
calculators that do statistical calculations for you will not be of much help.
You are not allowed to use
cell phones or computers during the exams.
Extra
credit: You
may earn up to 8 points of extra credit by participating in psychological
studies. Two percentage points will be added to your lowest exam score for each
credit earned on the researchpool system.
Signups
for research studies are now listed exclusively on the http://researchpool.towson.edu
website. To signup for studies, you will need to create an account. Please go
to the psychology department’s research participation webpage for more
instructions: http://pages.towson.edu/jbucking/participant.htm
(This page is also available via the Psychology Department Homepage).
Cheating and plagiarism: Don’t do it!
I will follow university procedures as described in the student academic
integrity policy.
For this course, the most
important behaviors to avoid are the following:
Copying from another
student’s paper (for homework or exams)
Knowingly allowing another
student to copy from one’s paper (for homework or exams).
Using books, notes, or other
devices when these are not authorized (i.e., on an exam).
