Methods are presented which make possible inferences about a population from knowledge of small samples. Students will be introduced to statistical techniques used to conduct scientific research. Methods of measurement and techniques available to summarize sets of data will be discussed. The course will stress an understanding of conceptual issues involved in the selection of statistical methods rather than memorization of formulas.
This course uses Blackboard Learn. Class announcements, lectures, labs, and grades are administered in Blackboard Learn. Also available in Blackboard Learn are the homework assignments (WebAssign), recorded lectures (Tegrity Recordings), and clicker registration (Clicker Registration).
By the end of the semester, students should be able to….
Goal 1. Descriptive Statistics
1.1 Distinguish between types of measurements.
1.2 Depict the results of a simple study.
1.3 Describe a distribution of data in terms of its shape, central tendency, and variability.
Goal 2. Inferential Statistics
2.1 Identify appropriate statistical procedures to use for analysis of a given data set.
2.2 Understand the basic principles of hypothesis testing.
Goal 3. Use of Data Analysis Software
3.1 Effectively use SPSS to compute descriptive statistics, construct graphs, and compare means.
3.2 Demonstrate proficiency in reading and interpreting output.
Goal 4. Statistical Reasoning
4.1 Interpret basic statistical results.
4.2 Demonstrate an understanding of the difference between probable and improbable.
4.3 Demonstrate an understanding of the role of chance in determining statistical results.
4.4 Distinguish between statistical and practical significance.
Attendance is required to receive participation points. However, attendance alone does not give you participation points. You must use your clicker while in attendance to receive participation points. See Exams and Assignments section.
1. Exams (240 pts; 60%). There are 4 required exams, each worth 60 points, for a total of 240 points. The first three exams are during regular class periods and the fourth is the final exam. You will need a #2 pencil and a calculator for each exam. Exams may include multiple choice questions, fill-in-the-blanks, short answers, and working problems. Exams must be completed within the scheduled class period unless plans have been made beforehand with the instructor. The final exam consists of two parts. The first part covers new material since the last exam. The second part is an applied comprehensive exam and will consist of descriptions of experiments for which you will have to decide which statistical test to use and explain why you chose it. There will be NO computations on this second part of final exam.
2. Lab Projects (80 pts; 20%). There are 14 lab projects: the first is worth 2 points and 13 are worth 6 points each, for a total of 80 points. Projects require students to work with data using SPSS, which is a statistical package commonly used in behavioral science research. Projects will be completed during the Friday lab. Friday labs meet in 16 Lloyd Hall.
3. Homework (40 pts; 10%). There are 13 homework assignments: 1 assignment per chapter, except two for Ch. 9. Assignments are completed online in WebAssign. Accessing WebAssign iw worth 1 point and each homework assignment is worth 3 points, for a total of 40 points. Homework should be completed by Friday of each week @ 5:00 pm to receive credit. Labs on Fridays are a great time to finish homework assignments.
4. Class Participation (40 pts; 10%). Students are required to participate in every MW class using their clickers. This is not an attendance requirement; rather, it is a participation requirement. PARTICIPATION IS DEFINED AS USING ONE’S CLICKER TO SHARE ONE’S RESPONSES WITH THE CLASS. Using your clicker at least once is worth 2 points; otherwise, there are 12 Mondays, each worth 2 points, and 14 Wednesdays, each worth 1 point, for a total of 40 points.
Caveat:
If you are experiencing circumstances beyond your control, please contact the professor or GTA as soon as possible.
There may be extra credit opportunities on an ad-hoc basis for exams, lab projects, and homework.

All students in attendance at the University of Alabama are expected to be honorable and to observe standards of conduct appropriate to a community of scholars. The University expects from its students a higher standard of conduct than the minimum required to avoid discipline. Academic misconduct includes all acts of dishonesty in any academically related matter and any knowing or intentional help or attempt to help, or conspiracy to help, another student.
The Academic Misconduct Disciplinary Policy will be followed in the event of academic misconduct.
The mission of The University of Alabama is to advance the intellectual and social condition of the people of the State through quality programs of teaching, research, and service. That educational mission is enhanced by the robust exchange of ideas that occurs within a diverse and inclusive learning environment. Students who learn from each other and from faculty members and administrators (including those at the highest levels of leadership) in an environment with a variety of backgrounds are better able to understand, appreciate, and contribute to our twenty-first century global society. Consequently, the University endorses a student, faculty, and administrative community enriched by women and men of diverse national origins, races, ethnicities, sexual orientations, cultures, socioeconomic and geographic backgrounds, ages, physical abilities, and religious and political beliefs. The University is committed to offering diverse cultural programs, intercultural education, and other educational initiatives (such as the Universitys Crossroads Community Center) that enhance awareness and appreciation of cultural and individual diversity, promote community, and prepare students for the global society in which they will live and work.
As an institution of higher learning, The University of Alabama attaches great value to freedom of speech and open debate, but it also attaches great importance to the principles of civility and respect which govern an academic community. Harassment or other illegal discrimination against individuals or groups not only is a violation of University Policy and subject to disciplinary action, but also is inconsistent with the values and ideals of the University.
It is the goal of The University of Alabama to cultivate a hospitable campus environment in which all members of the University can work together and learn from each other in a climate of mutual respect.
In the case of a tornado warning (tornado has been sighted or detected by radar, sirens activated), all university activities are automatically suspended, including all classes and laboratories. If you are in a building, please move immediately to the lowest level and toward the center of the building away from windows (interior classrooms, offices, or corridors) and remain there until the tornado warning has expired. Classes in session when the tornado warning is issued can resume immediately after the warning has expired at the discretion of the instructor. Classes that have not yet begun will resume 30 minutes after the tornado warning has expired provided at least half of the class period remains.
UA is a residential campus with many students living on or near campus. In general classes will remain in session until the National Weather Service issues safety warnings for the city of Tuscaloosa. Clearly, some students and faculty commute from adjacent counties. These counties may experience weather related problems not encountered in Tuscaloosa. Individuals should follow the advice of the National Weather Service for that area taking the necessary precautions to ensure personal safety. Whenever the National Weather Service and the Emergency Management Agency issue a warning, people in the path of the storm (tornado or severe thunderstorm) should take immediate life saving actions.
When West Alabama is under a severe weather advisory, conditions can change rapidly. It is imperative to get to where you can receive information from the National Weather Service and to follow the instructions provided. Personal safety should dictate the actions that faculty, staff and students take. The Office of Public Relations will disseminate the latest information regarding conditions on campus in the following ways:
