Syllabus: Statistics with R (200-level)

This course introduces students to the scientific approach to social studies. Weekly classes and tutorials are geared toward helping the students gain a basic understanding of systematic social inquiry. In the lectures, students learn about the fundamentals of quantitative research, and accustom to strategies for data analysis, hypothesis testing, and statistical inference. Each lecture is followed by a computer lab session, where students put their knowledge to practice, and perform tasks that revolve around visualizing data, and conducting statistical analyses.

Each session will start with a set of brief instructions on the use of the R commands. Students will then work on their assigned tasks under supervision. – A typical lab tutorial will focus on a particular homework assignment, due before the following Sunday, at 11:55pm, via the online platform. Students are required to complete all homework assignments using R, which can be downloaded for PC and Mac for free from https://www.rproject.org/ Penalty for Late Submissions – For late submissions, students will be assessed a penalty of 10% per each calendar day. – Late submissions will not be accepted after three calendar days. – Note: All submissions in this course are digital.

Syllabus, Statistics with R Page 2 of 10 Academic Dishonesty and Misconduct Policy All departments follow the university policy on academic dishonesty and misconduct procedures. All written assignments must cite sources, and include a bibliography that follows a citation style. It is the responsibility of students to inform themselves of the content of the aforementioned policies. Grade Appeals Only final grades or written assignments may be appealed. Grades may be raised, lowered, or remain unchanged upon review. – Students must first consult with their instructor, providing a written account of why their grade should be changed. The grade will be discussed with the instructor informally. – If Step 1 is unsuccessful, students should submit a completed grade appeal form to the Department Chair, along with all of the graded material being appealed. The Department Chair will arrange for a re-evaluation of the work in question and assign a new grade. – If a student feels their grade appeal has been dealt with inappropriately at the department level, they may convey their concern to the Dean, who will review and confirm the new grade assigned, or initiate an alternate means of reconsideration. The decision of the Dean shall be final, subject only to an appeal to Senate. Syllabus, Statistics with R Page 3 of 10 Course Schedule WEEK ONE Introduction. Univariate Statistics.
