4.0    COURSE OBJECTIVES

This course introduces students to research methodology and statistical analysis using the SPSS software package. Other computer applications for creating data files and conducting secondary analyses are surveyed briefly.

The lectures present a balance of the theory, the rationale, interpretation, and detailed examples of key univariate and multivariate statistical procedures.


The laboratories will provide students with the opportunity to conduct statistical analyses using SPSS and other secondary software packages and to report their findings using APA style reports. The laboratories will be conducted in the Department of Psychology Computer Laboratory (Rm 3133 SSC), where students will be able to work on their assignments with consultation with the course Teaching Assistant. Students are allowed to use the Laboratory at other times, when available, and also have access to the SSNDS Computer Instructional Laboratory (Rm 1020 SSC) to do their SPSS assignments for this course.

   4.1    STUDENT LEARNING OUTCOMES

By the end of this course, successful students will be able to:

  1. Recommend and justify an appropriate research design and statistical procedure for a given research question or hypothesis.

       2. Differentiate between the statistical procedures in terms of their permissible applications and the scale properties of the data.

       3. Generate hypotheses to address specific research questions.

       4. Analyze data using appropriate descriptive and inferential statistical procedures.

       5. Apply 10 different statistical procedures by analyzing data sets.

       6. Demonstrate their understanding of Type I and Type II errors by conducting simulated demonstration of such errors.

       7. Write research reports clearly and effectively in a way that a reader would have the necessary information to replicate the study. The quality of methods and result sections will match the level in good empirical journals.

       8. Describe, critique and justify their research methodology and generate ways to improve upon it.

       9. Demonstrate their capacity to work independently and in an ethical manner by producing their own written work and meeting the timelines for the 10 assignments.

5.0     EVALUATION

Laboratory Assignments: 50% in total (5% x 10 labs). There will be 10 lab assignments, each requiring a written report. These will be graded by the Teaching Assistant. All assignments must be handed in at the beginning of the lab session following the session in which it was assigned. Late assignments will not be accepted and will be given a grade of 0. The last assignment is due one week after the last laboratory session. Students are responsible for their own assignments—copying assignments constitutes plagiarism. The Laboratory Assignment grade is the mean grade obtained in the 10 assignments. These 10 assignments together constitute the written component of 2,500 words required for a half-year essay course.

Final Examination: 50%. The final examination will be based on all material presented in lectures, laboratories, and the assigned text chapters. All assigned text material, regardless of whether or not it was discussed in class, is eligible exam material. The final exam will be set by the Registrar’s office during the official examination period and will be 3 hours long. The exam format will include a mix of multiple choice items, short answer questions, and written interpretations of selected SPSS statistical results.


Although the Psychology Department does not require instructors to adjust their course grades to conform to specific targets, the expectation is that course marks will be distributed around the following averages:


70%     1000-level and 2000-level courses
72%     2190-2990 level courses
75%     3000-level courses
80%     4000-level courses
   
The Psychology Department follows the University of Western Ontario grading guidelines, which are as follows (see http://www.uwo.ca/univsec/pdf/academic_policies/general/grades_undergrad.pdf ):

A+  90-100      One could scarcely expect better from a student at this level
A    80-89        Superior work that is clearly above average
B    70-79        Good work, meeting all requirements, and eminently satisfactory
C    60-69        Competent work, meeting requirements
D    50-59        Fair work, minimally acceptable
F    below 50    Fail

LEARNING OUTCOMES, ACTIVITIES and ASSESSEMENT

 

Learning Outcome

Learning Activities

How

Assessed

 

Depth and Breadth of Knowledge.

 

Recommend and justify an appropriate statistical procedure to use for a given research question or hypothesis.

 

Differentiate between the statistical procedures in terms of their permissible applications based on the scale properties of the data.

 

 

 

Ten weekly labs are designed to develop applied knowledge of the statistical procedures. In each lab, a problem is presented with a data set or with a request to generate simulated data with specific properties. The labs are described in tutorials led by graduate student TAs. Students develop the research hypotheses, analyze the data, and write a research report.

 

 

 

The ten labs assess (in part) knowledge of the uses and applications of each statistical technique.

 

The final exam assesses the ability to select the correct procedure for specific problems.

 

Application of Knowledge.

 

Generate hypotheses to address specific research questions and analyze data using appropriate descriptive and inferential statistical procedures.

 

 

 

For each of the ten procedures presented in class, students have the opportunity in the weekly labs to apply the procedure to a real research problem that addresses real challenges such as violations of assumptions or lack of statistical power.

 

 

 

The labs assess the ability to use a specific procedure correctly in terms of addressing the assumptions, and reporting and interpreting results.

 

The final exam does the same but presents research problems in which students must justify using a specific procedure.

 

Application of Methodologies.

 

Apply 10 different statistical procedures by analyzing data sets.

 

Demonstrate their understanding of Type I and Type II errors by conducting simulated demonstration of such errors. 

 

 

 

In each lab, students learn to apply a statistical procedure in SPSS, including preparation of the data file, syntax statement, selection of specific secondary tests of assumptions, interpretation of the output, and how to synthesize the extracted information into a report.

 

 

 

Students need to master the correct way to interpret and report results from software output. This is assessed in the lab reports and in the exam.

 

 

Learning Outcome

Learning Activities

How

Assessed

 

Communication Skills.

 

Write research reports clearly and effectively in a way that a reader would have the necessary instructions to replicate their study and the necessary information to interpret their results.

 

Write method and result sections that match the level in good empirical journals.

 

 

 

Students have the opportunity to develop their research writing skills through weekly reports and receive weekly written feedback from their TAs. This structure helps address timely correction of problems or fine tuning of writing format in specific areas of the report.

 

 

 

The labs assess students’ ability to think and write clearly.

 

The section of long answers on the exam also assesses the ability to communicate an idea clearly.

 

Awareness of Limits of Knowledge.

 

Describe, critique, and justify their research methodology especially in the discussion section of their research reports.

 

Generate ways to improve upon their research methodology.

 

 

 

 

Feedback from TAs on the lab reports highlights any needed correction in the interpretation of results and limitations. The lab assignments include questions that specifically address the limits of what can be concluded from the results.

 

 

 

 

The lab reports also assess the ability to present justified conclusions along with their limitations.

 

Autonomy and Professional Capacity.

 

Demonstrate their capacity to work independently and in an ethical manner by producing their own written work and meeting the timelines for the 10 reports.

 

 

 

 

Students are responsible for 10 weekly lab reports, and must produce their own original reports.

 

 

 

 

Late reports receive a deduction and originality of work is assessed in adherence to the institutional policies for plagiarism.

8.0     STATEMENT ON ACADEMIC OFFENCES

Students are responsible for understanding the nature and avoiding the occurrence of plagiarism and other scholastic offenses. Plagiarism and cheating are considered very serious offenses because they undermine the integrity of research and education. Actions constituting a scholastic offense are described at the following link:  http://www.uwo.ca/univsec/pdf/academic_policies/appeals/scholastic_discipline_undergrad.pdf

As of Sept. 1, 2009, the Department of Psychology will take the following steps to detect scholastic offenses. All multiple-choice tests and exams will be checked for similarities in the pattern of responses using reliable software, and records will be made of student seating locations in all tests and exams. All written assignments will be submitted to TurnItIn, a service designed to detect and deter plagiarism by comparing written material to over 5 billion pages of content located on the Internet or in TurnItIn’s databases. All papers submitted for such checking will be included as source documents in the reference database for the purpose of detecting plagiarism of papers subsequently submitted to the system. Use of the service is subject to the licensing agreement, currently between Western and Turnitin.com http://www.turnitin.com

Possible penalties for a scholastic offense include failure of the assignment, failure of the course, suspension from the University, and expulsion from the University.
