ST 311_601 Fall 2021 IMPORTANT!! Your grade will be determined by your performance in three required assessment activities: 1). Homework that can be accessed at https://www.webassign.net 2). Mastery Points that can be earned at MyLab and Mastering accessed using the VitalSource app link on our Moodle page. 3). Exams: two midterm exams and a final exam taken locally at the DELTA Testing Center or arranged at a remote site. For more details see How Your Grade is Determined on p. 6.

Final Exam Window/Mastery Points Deadline: Final Exam Window: Thursday December 2, 2021 –Wednesday December 8, 2021. Mastery Points Deadline: Monday November 29. **WARNING! WARNING!** Do not over-schedule! This course requires at least as much of your time as a traditional lecture-driven course. Do NOT assume that it can be ignored in your time-management plans for the semester just because it is a distance education class. Be realistic in your planning; for example, you probably cannot take 16 hours and work 2 parttime jobs just because this course constitutes 3 of the 16 hours. As we proceed through the semester remember that procrastination on your part does not constitute an emergency on my part. READ ALL THE INFORMATION BELOW. CAREFULLY FOLLOW THE INSTRUCTIONS FOR OBTAINING THE COURSE MATERIALS USING THE ALL-IN PROGRAM AT THE NCSU BOOKSTORE. ***************************************************************************************** COURSE INFORMATION QUICK-FIND TABLE (point to link and press Ctrl+click) Course Text Webassign Homework

********************************************************************************************** ST 311_601 is a self-paced (to some extent) course during the semester in which it is offered. Due dates for the webassign homework will assist you in maintaining a steady work pace throughout the semester. Since topics later in the course depend on material introduced earlier in the course, you would find yourself quickly overwhelmed if you attempted to cover everything in a short period at the end of the semester.

Mark your calendars with the webassign homework due dates and the exam windows shown elsewhere in this document. In addition, click Notifications and follow the directions to receive email homework due date reminders from webassign. Procrastination on your part does not constitute an emergency on my part.

SOFTWARE: EXCEL AND STATCRUNCH

ST 311_601

Course Information

Statistics is not a spectator sport! In this course you will be doing statistics rather than listening to someone talk about doing statistics. The main tools that will facilitate your involvement are one or more of the following: Excel, your graphing calculator, if you have one (you do not need to purchase a graphing calculator for this course), or Statcrunch. It is very important, especially for Mac users, that you read the information in the Computers/Calculators section of our class webpage concerning the use of Excel and Statcrunch. Statcrunch is available online at two locations: 1) http://statcrunch.stat.ncsu.edu/ (Unity login required), and 2) our MyLab Statistics website accessed using the VitalSource app link on our Moodle page (click on “Statcrunch” in the left column of the MyLab Statistics website, then click “view data from text”). Statcrunch is a cloud-based award-winning spreadsheet-type statistics program that is superior to Excel in many aspects for doing Statistics. You will use Excel and Statcrunch in many of the homework problems to analyze interesting real-world data sets included with the problems. After completing this course many students have found Statcrunch to be very useful in subsequent courses and in their workplace. HOMEWORK The homework activity consists of two required components: 1) 12 webassign homework assignments; 2) 15 mastery points earned by taking 5-question quizzes at the ST 311-601 Introduction To Statistics Fall 2021 MyLab Statistics website accessed using the VitalSource app link on our Moodle page website. A mastery point quiz consists of a few questions associated with a specific textbook chapter objective. See the Course Information section below for more details concerning the webassign assignments and mastery points. Students are encouraged to discuss the homework problems; you can learn a great deal from each other. Each webassign homework assignment will have its own forum on webassign to encourage and facilitate discussion of the homework. However, the actual submissions of the answers must be done independently. WEBASSIGN HOMEWORK DUE DATES There will be twelve 30-point assignments during the semester with due dates shown below. Each assignment must be submitted by 11:59 pm on the due date. After its due date an assignment can still be viewed along with its answer key but answers cannot be submitted. Webassign at https://www.webassign.net will be used to administer the assignments. Assignment Submit No Later Than: Webassign homework 1 Mon. Aug. 23, 2021 Webassign homework 2 Sat.

Course Description: ST 311-601 is NOT a math course. The central theme of the course is to help you learn to understand the world from data. Specifically, the course will enable you to: i) incorporate statistical thinking into your everyday lives; ii) acquire the necessary data-gathering, data-analysis, and interpretation/communication expertise to meet the challenges of a more demanding cognitive global environment. “Beyond the formula” skills are emphasized. This course will require you to: think critically, be skeptical, think about variation (rather than just about the center), move beyond a “memorize the answer” approach, and think about conditional probabilities and rare events (humans just don’t do the latter very well). Some mathematical skill is required to work with elementary statistics (basic high school algebra is the mathematical prerequisite), but mathematical manipulations will be replaced by relying on technology for the calculations and graphics; this will allow more emphasis to be placed on the “beyond the formula” skills mentioned above. This course requires more intellectual effort than the low mathematical level suggests! It is related to every other course you may study. The course is elementary in mathematical level but conceptually rich in statistical ideas and serious in its aim to improve your data-analytic skills and your ability to apply statistical methods with understanding. You can tailor the course to suit your particular learning style by “mixing and matching” the many traditional and multimedia learning aids available at our MyLab Statistics website. The Stats: Data and Models text has short, teachable chapters and an approachable, colloquial style that makes the text very readable. The MyLab Statistics website matches the organization of the Stats: Data and Models text and includes a high quality interactive ebook with links to a wide variety of resources available to students.

Back to Quick-Find Table Academic Integrity Policy: Any form of academic misconduct is a violation of the Student Code of Conduct and will not be tolerated. Academic misconduct may be defined as "any activity which tends to compromise the academic integrity of the institution, or subvert the educational process". I expect complete honesty in the completion of webassign homework and tracked tutorial exercises. The student's electronic submission of assigned work means that the student neither gave nor received unauthorized aid. Cheating on an exam or webassign homework at the least will result in an F in the course. Students are encouraged to discuss webassign homework and tracked tutorial exercises with each other; however, submission of the answers must be done independently. Violations of this rule will not be tolerated and will be considered cheating. Further details on academic integrity are in NC State University's Code of Student Conduct at http://www.ncsu.edu/student_conduct. Also note the existence of the University policy on academic integrity found in the Code of Student Conduct (in Appendix L of the Handbook for Advising and Teaching and at University Policy on Academic Integrity (see paragraphs 6 and 9).

For grade determination purposes, each midterm exam is 150 points and the final exam is 200 points; each webassign homework has 30 possible points; each “mastery point” is worth 10 course points. The point totals for each component are shown below:  Exams 500 points (2 midterms: 150 pts. each, final exam: 200 pts.)  Webassign homework 360 points (12 assignments @ 30 pts. each)  Mastery Points 150 points (15 mastery points @ 10 pts. each) Total 1010 points Your grade in the course is assigned according to the percentages shown in the table below. The percentage score, rounded to 2 decimal places, is determined by summing your exam score (500 total points possible), your webassign homework score (360 total points possible) and mastery points (150 total points possible) and dividing this sum by 1010. The webassign homework is posted online at webassign, https://www.webassign.net. The “mastery points” are earned by passing short auto-generated quizzes at the ST 311-601 Introduction to Statistics Fall 2021 MyLab and Mastering website accessed using the VitalSource app link on our Moodle page (click on Mastery Points in the left panel at the MyLab and Mastering website).
