I don’t want you to be a mini-me, I want you to be a best-you. By the end of the semester, you should be comfortable updating your CV with this sentence:

Out of Class:
In Class:
Introductory video: This video provides an overview for the topic and will be featured on the homework.
Homework: Every unit has a homework assignment in Blackboard. You have three attempts at each homework assignment. The questions will differ slightly for each attempt. Your best score will be recorded as your grade.
Work towards mastering formulas/JASP/theory: Make sure that you understand the formulas you learn in class, how and when to use them, and what you get from the formula. Also, understand how to use and interpret any work performed in JASP.
Come to class ready to learn: In class, I will discuss each topic in depth. Together, we will work through calculations and JASP, learn to communicate statistics, and learn the theory behind the data.
Microassignments: Periodically, I will give you a microassignment for credit. I might ask you to upload some of your in-class work to Blackboard, or post you answer to a discussion question in Bb.
Not-in-my-office hours: These will be held in the basement of the library. Your instructor will be prepared to lecture, review, and answer questions. All are welcome for however long you care to stay. Food is allowed. You don’t even need to have any specific questions in mind. Just come. Tuesdays, 12:30-3:00, usually in Nash 203 or 204.
What do I need to do?
This is what you should do for each of the 13 sub-units

How your success is evaluated in this class:
During class, you will log into Bb and answer questions about statistics, yourself, and life. Why? I don’t like attendance points based on simply showing up to class. I want to touch base with you and see how you are doing.
Mini assignment
Your 13 hw assignments are available on Bb. You have three unique attempts at each hw. After each attempt, you can view the questions you answered incorrectly but you won’t be given the correct answer. Your highest scoring attempt will be your grade.
Use as many attempts as you need to practice your statistical skills. Due at 12:15 PM on the due date.
This class uses five exams to assess your performance. They are timed, open-book, open-note exams via Bb. You must work independently on the exam. The final exam is NOT cumulative

Disability Accommodations: The University will make reasonable accommodations for students with disabilities in compliance with Section 504 of the Rehabilitation Act and the Americans with Disabilities Act. The purpose of accommodations is to provide equal access to educational opportunities for eligible students with academic and/or physical disabilities. Gannon students who require accommodations due to a documented diagnosed physical, emotional or learning disability should contact Gannon’s Office of Disability Service at extension 5522 or find more information at:
Policy on Resolving Concerns with an Instructor: If you have a concern with an instructor or a course, the resolution begins by speaking with the instructor. If the concern continues after this conversation, the student should speak with the chair/director of the instructor’s department. Any continuing concerns should be taken to the Dean’s Office.
Academic Integrity Policy: Gannon University has a Code of Academic Integrity that defines areas of cheating and the procedure for dealing with violations. Students should be aware that failure to comply with the University’s standards as set forth in the academic integrity code may result in punitive measures that are not limited to but may include assignment failure, course failure, program suspension, university suspension, or separation from the university.

“One thing that helped me do well in this class was studying with someone else in the class.”
Being able to practice running tests in JASP really helped me prepare for the exams
“One thing that helped me do well in this class is following along and doing the examples with Dr. Hartnett when she is first showing us how to do them in class. That way I can ask questions as soon as they come up.”
“One thing that helped me do well in the class was to watch the crash course videos twice. I would watch it once for information and then a second time to take notes to study off of.
“I think that the homework assignments are really beneficial if you take the time to correct your mistakes. I thought it was best when I tried the homework once and then reviewed the powerpoint, notes, etc. before giving it a second or third try.”
“One thing that helped me do well in class was reviewing every practice problem from each section by redoing the JASPs and APA write-up. I also studied each section of notes through the course of several days.”
“One thing that helped me do well in this class was really paying attention during the review days before the test when Dr. Hartnett would use examples that were more familiar to us, like Hunger Games and Harry Potter data. Being more familiar with that data and then using it to assess statistical tests helped everything click together.”

When life gets hard | I have had students lose parents, grandparents, and friends mid-semester. I have had students who were in car accidents, were assaulted, dumped, diagnosed with mono, served as legal guardians to younger siblings, suffer physical injuries, been robbed, have legal issues, have a parent on a transplant list, have chronic mental and physical problems, have transportation issues, have food security issues, get pregnant, give birth mid-semester, get COVID, etc. I have taught student athletes. I have taught students who work 40 hours a week. I have taught parents. I understand that even without crisis situations, you are all very busy. I want all of my students to succeed academically and personally. The two are intertwined. If you are having trouble this semester for any of the reasons listed above, or any other reason, I am here to work with you.
