The Internet home page for this course is http://www.psych.purdue.edu/~gfrancis/Classes/PSY201/indexF17.html This class does not use Blackboard.

IntroStats Online at https://introstatsonline.com. This is an on-line textbook that requires a login. You will receive information on setting up and registering an account from the instructor. You will be graded for finishing the readings by the assigned day and time (always 10:00 am). A rough outline of the readings is given below. Precise readings (sections and their due dates) are given at the textbook site. Each assignment must be completed by the assigned date and time. The textbook grade counts as 10% of your class grade.

The IntroStats Online text includes end-of-chapter homework assignments. The rough schedule is below, with precise details (which questions) at the textbook site. All homework assignments must be completed by 10:00 pm on the due date. The homework will make up 20% of your final grade.

StatLab assignments
Also included with your textbook is access to a web site called StatLab Online. A StatLab account, with the same login credentials, will be created when you sign up for your IntroStats Online account. You will be given StatLab assignments throughout the semester that measure some aspect of your behavior. They are run through the Internet and can be carried out at any computer lab on campus or at a home computer. At the end of each experiment you will need to calculate statistics that are appropriate for the experimental results. You get credit by finishing the experiment and answering all of the statistics questions correctly. Your overall lab grade will make up 15% of your final grade. In the schedule below, individual labs are associated with different dates. You must complete the lab by 10:00 pm on the date indicated to get credit. You will find that computing the statistics is easiest if you copy and paste the data into a spreadsheet such as Microsoft Excel. If you have not previously used Excel, you may want to look over a tutorial to get started. Sorting is especially useful, and unfortunately is not covered in the previous tutorial.

Class attendance: Your presence for the lectures is mandatory, and will be checked each class period. Over the course of the semester, each student may miss up to 6 lectures without penalty. Additional absences will proportionally reduce your class attendance score. This score contributes to 5% of your final class grade. Athletes and other special cases need to contact Dr. Francis.

There will be three section exams and a final exam. The section exams will be in-class and the final exam will be given during the final exam period. Each section exam is worth 10% of your grade. The final exam is worth 15% of your grade, it will cover all topics of the course, and it is taken during the scheduled final exam period. Make-up exams will not be permitted unless you check with Dr. Francis at least 48 hours prior to the scheduled exam date to verify that your excuse allows you to take the exam at another time. Missed exams will receive a grade of 0. Study guides are available as links in the class schedule below.

Practice exams
Prior to each exam you will be given a practice exam (from Fall 2015). You must complete the practice exam and submit it to the TA for feedback by the date indicated in the schedule, below. Your grade on the practice exam is whether you complete the assignment, it is not based on the graded score of the practice exam. Completing the practice exams is worth 5% of your final class grade.

The number links on the far left of the schedule (below) are to PDF copies of the lecture notes.
