# STAT 2000

PROSPECTIVE FALL 2023 STUDENTS: ANSWERS TO FREQUENTLY ASKED QUESTIONS

Every section of STAT 2000 has the same tests, quizzes, homework, labs, and due dates. Sections only differ by primary instructor. If my name appears anywhere on the course you have signed up for in Athena, I am the primary instructor. If you see Nick's name twice on your schedule, then Nick is your primary instructor.

In-person lab attendance is required on the lab date and time that you signed up for in Athena. Lecture attendance is not required. While we will not penalize you for not attending class, you are still responsible for what is said in lecture. You will need to catch up on your own in eLC if you are absent.

You will need to score 100% on the syllabus quiz to access course content in eLC. The entirety of this course is in eLC (lecture videos, notes, examples, practice problems, module goals, etc.) Passwords to most locked assignments are in eLC.

The syllabus is your friend. This is a very large course which results in a large number of student emails. I typically answer administrative questions that were already addressed in class or in the syllabus at the very end of the week.

The syllabus has accommodations for emergencies built into it. This should not be interpreted as, "I only have to take 3 of 4 quizzes" or "I only have to attend 8 of the 10 labs." Emergencies do happen, so do not waste your built-in safety net!

This course requires working knowledge of the math you learned from elementary school all the way up to Algebra I (solving equations) and an ability to convert words into mathematical symbols. I teach many of these K-12 topics quickly & explicitly to ensure student success. Please note that I am not required to do this.

About me: I do not teach tricks that are devoid of mathematics. I teach conceptually. While we skip much of the underlying calculus and analysis that are the theoretical underpinnings of statistics, conceptual understanding is required to be successful in this course and interpretation is critical. I have students work on problems in class so that they can identify areas of difficulty and inform me in the moment.

There are a plethora of black-box point-and-click statistics programs and apps that can solve problems for you. Exams are often written in a manner that makes these programs useless. Focus on learning conceptually and you will be fine. Math should make sense and I love working with students to ensure that the math makes sense for them. I offer office hours in abundance to help meet this goal. If my typical hours do not work for you, make an appointment.

If all of this sounds good to you, feel free to sign up for my class!

Take the syllabus quiz on eLC immediately. A 100% is needed to access course notes on eLC.
