Psychology 2013: Introductory Statistics

This course will examine descriptive and inferential statistics that are used to organize, summarize, and interpret psychological information. Topics to be covered include frequency distributions, measures of central tendency and variability, z scores, normal distribution, sampling distribution of means, hypothesis testing, one sample tests, two sample tests, correlation, and nonparametric tests.

Textbook: Gravetter, F., & Wallnau, L. (1999). Essentials of statistics for the behavioral sciences (3rd ed.). Pacific Grove, CA.: Brooks/Cole Publishing.

Calculator: Students should bring a calculator to each class after the first week of classes. The calculator should be able to add, subtract, multiply, divide, and square root.

Tentative schedule of chapters, quizzes, and exams

Quiz 1 - Lectures and parts of preface and chapters 1, 2, and 3
Test 1 - Lectures and chapter 1, 2, 3, and 4
Quiz 2 - Lectures and chapter 5 and 6
Test 2 - Lectures and chapters 5, 6, 7, and 8
Quiz 3 - Lectures and chapter 9 and 10
Final exam as scheduled by registrar Chapters 11 & 15, lectures, and all of the above information

Each quiz is worth 5%. Each test is worth 15%. The final exam is worth 35%. There will be no opportunity to write any make up quiz. A student's score on each quiz can be replaced by the percentage that he or she earns on the immediately following exam if either the student earns a higher percentage on the exam or the student misses the quiz and has an excuse acceptable to the instructor. If a student misses a test and has an acceptable excuse, the make-up exam will be over all information covered in class up until the student writes the make-up exam. A student's score on the final exam can replace one of the earlier exams if the student scores higher on the final exam than either of the earlier exams.

Assignments

There will be several assignments. Together homework assignments are worth 15%. On each assignment there must be a title page with the student's name in the upper right hand corner of the title page. Unless the student has an acceptable excuse, the value of a late assignment will decrease by 10% per day until that assignment has been returned in class. Once an assignment has been returned, that assignment will not be accepted for course credit. If a student has a valid reason for missing an assignment, then the student will be given an opportunity to complete an alternative assignment.

Class participation

Class participation is worth 5% of a student's grade. Class participation will be evaluated on quality of questions asked, quality of answers to questions, whether students are prepared to work on problems in class (i.e., whether they have a calculator, statistical tables, etc. with them), work on assigned problems in class, class notes, etc.
