COURSE OVERVIEW: In today’s world, we find “big data” driving decisions made in every aspect of life. Statistics is a discipline dedicated to unraveling the mystery of making such decisions when faced with uncertainty. More precisely, statistics is the art and science of using sample data to make generalizations about populations. The objective of this course is to explore and apply basic statistical concepts and procedures that are used when analyzing data. What you should discover is that statistics is not just another math course. While you will be exposed to new terminology and concepts, much of the time you will use statistical software to solve problems that require quantitative solutions. Math is said to be the language for communication with both science and much of the social sciences. Statistics provides the structure for this communication. You will not be inundated with repetitive calculations but instead will explore data with a context. Basic algebra is the only prerequisite. The second part of the course is more technical. Success in this course requires an ability to apply reasoning skills over memorization. Additionally, you will need to integrate new material with previously-learned material throughout the session. You are strongly encouraged to read newspapers where you can see how statistics can be applied to every-day life. 1 COURSE GOALS: The two overarching goals are to: 1. understand the scientific method from a statistical perspective be able to identify questions, collect evidence, discover and apply tools needed to interpret the data, and communicate results. While you may never conduct a scientific study, it is still possible that you may encounter data or statistical results over the course of a career. 2. become good “statistical” citizens be able to: examine the information that you are inundated with, think critically about it, and then use it to make good decisions COURSE WEB SITE (ANGEL): https://cms.psu.edu: On the Angel web site, you will find: Syllabus, Course Calendar, Weekly Roadmaps, Grade Book, Exam Study Guides, Lecture quizzes Lab activity quizzes & Homework’s quizzes (also available at a later time for practice) Power point slides (bring to lectures) & Lab activity handouts (bring to lab) Announcements & email correspondence (check Angel email daily during the week) Course Learning Goals (Common Final will include a question from each learning goal) COURSE CALENDAR & WEEKLY ROADMAP: Course Calendar: provides dates for all exams, lab quizzes, & homework’s for the entire semester Weekly Roadmap: includes readings and assigned homework problems, etc. GRADES IN ANGEL GRADE BOOK (Angel does not loose grades): based on points (not percent’s) - select “grades” with category under Repots assessments linked to the grade book will show a grade of “0” until a submission COURSE AGREEMENT: This syllabus serves as an agreement that begins on the first day of class & ends upon completion of the final exam. With this course, you must: accept that: 1. this is an in-residence course/ you can’t disappear for days/weeks expecting to make-up work 2. final grades are: earned based on mastery of material (not on attendance or negotiations) - not changed for financial aid and/or academic progress purposes. (also not curved or rounded) - individual extra credit will not be allowed either during or after the end of the semester 3. during class cell phones should be put away as a matter of respect to the instructor 4. lab activities & LAQ’s must be completed during the scheduled time in the assigned lab room 5. all exams, including the final, must be taken at the scheduled time (can’t take early) 6. your iclicker must be: correctly registered & properly working (including good batteries) 7. instructor does not answer questions about grade calculations or clicker issues by email 8. you must seek immediate help if having problems 9. you must sign up for exams and follow rules when using the computerized testing center 10. the instructor is not connected to and does not provide answers/ solutions to problems developed by external money-making sources such as Lion Tutors, Nittany Notes etc. 11. you must submit your own work – don’t just copy from classmates use Angel: 1. with an acceptable browser and fully functioning internet connection 2. to send email; under the “Quick Message” option (no response to emails received outside Angel) with polite and acceptable greeting (includes name), complete sentences, and clear subject line 3. to regularly check: the grade book right after making a submission or posting (can’t report problems days/weeks/months later) - Angel does not lose grades come to class: at the scheduled start time, prepared to learn, willing to make the appropriate commitment PENN STATE Expectations include: _____ practicing academic integrity owning individual responsibility for your academic progress maintaining social and personal responsibility respecting the dignity of everyone in the Penn State community 2 ACADEMIC INTEGRITY: Academic integrity includes a commitment to not engage in or tolerate acts of falsification, misrepresentation or deception.

Richardson 5 Some Helpful Tips Provided By Previous Students: 1. Pay attention in class - and always ask if you do not understand something. It’s better to ask than to no know at all 2. Doing the lecture quizzes and optional homework is definitely what contributed to me getting over 100% in the course, 3. Come to class. Take notes firstly, and then spend more time on reviewing. Convert the lecture "words" into your own understanding 4. Do lecture practice quizzes soon after the lecture to reinforce the material you just learned. It helps to remember the information if you process it more often. 5. Be sure to constantly review notes and consult your teacher as soon as any problems occur. Since this course constantly builds upon itself, getting lost early on makes material confusing. Be sure to review, make flow charts and also meet with the TA; s. 6. Take LAQ’s and homework’s seriously – do practice quizzes – great study tool 7. Go to class every day, don't fall behind. 8. Do the practices offered on Angel, and keep up with classwork. Find people to work with and help each other out! 9. Come to all classes, so you will know the entire subject for the tests. Also, if it is possible, do all homework and Labs. Print the slides, labs, and read the chapter before classes also is a helpful tip. 10. Study the notes every day and redo all the lecture quizzes and lab quizzes 11. Follow along attentively in class. Do all homework’s and attend class regularly. 12. Use all the practice quizzes – listen in lecture and take good notes 13. I would recommend you to understand how all the material fits together, instead of just its individual components. Also to go consult the TA and other people in the class with questions. Definitely come to class and take the labs seriously because they help to solidify the information that you have learned in class. Attend and pay attention in class.
