**PROSPECTIVE STUDENTS: ****ANSWERS TO FREQUENTLY ASKED QUESTIONS**

Every section of BUSN3000 has the same tests, quizzes, homework, and labs. Sections only differ by primary instructor.

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.

The syllabus is your friend. This is a medium-large course which results in many student emails per day. I typically answer administrative questions that were

**already addressed in class or in the syllabus****at the very end of the week.**About me: I do not teach tricks that are devoid of mathematics. I view mathematics as necessary for the long-term evolution and safety of society and as a civil rights issue. When I teach, my goal is that students will find the mathematics to be so full of common sense that they can pass the class and go on to med school, breeze through industry data analytics interviews, or conduct independent analyses of problems within their own businesses.

While we skip much of the underlying calculus and analysis that are the

*theoretical underpinnings*of statistics, I do teach conceptually. I have students work on problems in class so that they can identify areas of difficulty and inform me in the moment. JMP is used extensively, but it is imperative that you understand what JMP is calculating and how to interpret it.**Big hint:**Many of the topics of this course come up in FAAMG interviews. Knowing how to use JMP will not suffice for getting through such interviews. Pay attention in class and read your slides; you will be fine.There are a plethora of black-box point-and-click statistics programs and apps that can solve problems for you. Exams may contain problems that make these types of 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!
