Quiz for Chapter 1:
1/5/2017

Quizzes in this class are neither graded, turned in, nor counted toward your grade in the class. The purpose of the quizzes is for you to get feedback about whether you are mastering the content in the class. The quizzes are a sample of the material covered in the book and in class; do not assume that just because you did well on a quiz that you have mastered everything. The quizzes will help you the most if you try them on a regular basis. Do not wait until just before an exam to take the quizzes.

You can take the first quiz at any time. You can take the quiz multiple times. When you are done, click on the Check Answers button at the bottom of the quiz. If you missed one or more questions, a pop-up box will give you the correct answer for each question. When you get a question wrong, you will learn more if you try to figure out why that answer is incorrect and why the given answer is correct. If you have questions about a question, you can ask me about it at the start of class. Be sure to write down the question id number (qid) that is given in the pop-up box. I will need the qid in order to see that particular question when you ask about it.

Assignment for Chapter 1:
1/5/2017

Like quizzes, assignments in this class are neither graded, turned in, nor counted toward your grade in the class. The purpose of the assignments is for you to get feedback about whether you are mastering the content in the class. A class period or two after I post the assignment, I will post the worked answers to the assignment for you to compare your work to. If you have questions about an assignment question, please let me know. Waiting until the week before the exam to do the assignments is a really bad idea.

The assignment for chapter 1 is here.

Lecture Notes:
1/5/2017

Copies of the PowerPoint slides are available from the Today link in the list of links on the left. You may need to scroll up or down on the Today page to find the lecture notes for a given chapter. It is your responsibility to print out the lecture notes (if you want them). I will not go slow enough during class for you to copy down everything that is displayed by the projector. Spending your class time copying the notes is a poor use of your time. Rather, listen and write additional notes in your own words.

The Textbook:
1/5/2017

The textbook is Gravetter and Wallnau's Statistics for the Behavioral Sciences, 10th edition . The book is required for the course. If you don't like the price of the book at the bookstore, cheaper options might be available at the publisher's web site or through the UD Textbook Comparison Shopping tool. If you are using an online bookseller, make sure you search for ISBN: 978-1-111-83099-1. You need the book now -- pay for the one or two day shipping.

Welcome!:
1/5/2017

Welcome to PSY 216, Elementary Statistics.  This will be a very important class in your undergraduate career as a psychologist in training.  Why?  First, you need a strong background in statistics in order to do well in PSY 217, Experimental Psychology and to understand the results of studies that are presented in content classes.  But more importantly, statistics allow psychologist to interpret the results of studies.  These results often improve our theories of psychological phenomena and improve the treatments that we can offer people with psychological disorders.  Even psychologists who do not perform studies need to understand statistics, as psychologists are ethically obliged by the American Psychological Association to stay current in their areas of expertise; to do so requires reading journal articles which often contain the results of statistical analysis of data.  Even if you will never be a psychologist, statistical expertise is a characteristic that employers look for when they interview psychology majors for jobs.

I hope that you enjoy the semester and our exploration of elementary statistics (yes -- there are many other statistical methods that are much more advanced that what we will cover.  Some of them you will learn about in graduate school -- most Ph.D. programs in Psychology require at least one year of graduate course work in statistics.)  Don't get behind in class, and ask questions when you have them.
