Course Description

In contrast to the most widely used statistical package programs, R, which is free of charge and open source, has an active structure that is constantly evolving with the contributions of researchers from around the world. Thus, R is an ideal tool while analysing the main statistical concepts of descriptive statistics and inferential statistics. From this point of view, the main aim of this course is to provide students with adequate knowledge in both programming in R software and theoretical statistical concepts. Hence, students will be able to use R in their statistical analysis related to their field of research.

Course Outcomes

Upon the completion of this course, the student will be able to:

  1. comprehend knowledge in working with R software for statistical analysis.
  2. interpret the results of the research according to the statistical methods applied to data.
  3. utilize the R for describing and analyzing the quantitative data.
  4. understand and apply mathematical concepts and reasoning, analyze and interpret various types of data.
  5. have the working ability both individually or as a group member.
  6. make the accurate presentation of the results in the framework of science and ethics.
  7. conduct a research related to real-world context.

These course outcomes will be assessed by 5 short exams, 1 mid-term exam, 1 term-project and 1 final exam. Details are stated in assessment methods and evaluation part of the syllabus.

AVL Learning Outcomes:

Assessment Method(s) and Evaluation

Grading will be based upon 10 short exams, 1 mid-term exam, 1 term-project and 1 final exam.

Mid-term and Final Exam

The mid-term and final exams are 20% and 40% final average, respectively: This assignments may be comprehensive in material and consist of a mixture of multiple choice questions and short essays or problems and lots of data analysis. Questions in the exams are designed to make sure that students comprehend the topics lectured and the analyses made with using R. These exams will cover lecture notes, lab exercises and any assigned readings. The types of questions on the exams will be similar to those asked in the study questions, lab exercises and the lecture materials covered during the semester.

Term Project:

This is 20% of the final average: This assignment is aimed to improve the ability of students in using R and interpret results of the research properly.
-The detailed information about the content and schedule of the term project is given in supplemental information part of the syllabus.

Short exams:

This is 20% of the final average: Students are required to complete 5 short exams throughout the course by means of the portal. The short exams includes 5 short work questions covering a specific chapters. These assignments cannot be made up after the deadline of each particular short exam. There will be no make-up exam for short exams.

Policy on Make- ups: Make-up examinations will only be administered to students with excused absences. Excused absences include death in the immediate family, University sponsored trips or critical illness. Verification is required and permission to miss an examination must be secured PRIOR TO the scheduled examination time. If this condition is not met, a zero will be given for the missed exam.

Grading
Grading Scale
Grade Quality Points
A = Excellent 90 – 100%
B = Good 80 – 89%
C = Satisfactory 70 – 79%
D = Passing 60 – 69%
F = Failing below 60%
Incompletes- I

Incompletes (I) demonstrate that a student was doing sufficient work at the end of a semester period but, for reasons beyond the control of the student, was unable to complete all requirements of the course in the related semester. The grade I obliges student to complete all course requirements within a time period that is specified by the instructor. This time period can’t exceed one academic calendar year from the end of the semester in that the grade I is assigned. The students has to arrange with the course instructor in order to complete all course requirements in a specified time period. If all course requirements are not completed by the students in a specified time period, I is changed to the grade F, unless the instructor has assigned a different grade.

Withdrawals-W

Students may withdraw from courses following the drop and add period until mid-term by completing the withdrawal process on the portal. A grade of "W" will appear in the student's official records if the student has withdrawn according to the SFU’s Withdrawal Policy. (Please see the SFU’s Withdrawal Policy for details.)

Attendance Policy

Participation and consistent attendance is essential for acceptable performance in the course. The students are expected to be present each class period except when special hardships occur, e.g. death in the immediate family, University sponsored trips or critical illness.
Regulations for attendance of Suje Florida University will be applied for this class.

Academic Integrity

Academic integrity is the responsibility of all Suje Florida University faculty and students. Cheating and plagiarism are not tolerated and will result in a failing grade, if the student is found guilty of cheating. All students are expected to do the work on their own and to accept standards of academic ethics.

Suplemental Information Statement

Term Project

  • In order to complete this course with a passing grade you will have to submit a term project that includes a detailed data analysis.
  • You will need to use R to present data, estimate models and make a prediction.
  • Students will be organized into groups of maximum three students each (Some group may have less depending upon the enrollment).
  • The term project topics will be assigned to the groups by the third week of semester or each group has the option to determine their own topic which must be approved by the instructor. The topics should be in the fields of aviaton logistics, business analytics or data science. (Due to the fact that this course is offered to all master programs in Suje Florida University, the topic can differ according to the master program that students are enrolled in the University.)
  • There are various deadlines for the term paper that you need to meet. These are presented and discussed below.
  • Timeline of your project will be as follows:
    Task Deadline How
    Group Creation 2.week e-mail
    Pick a topic (or get approval) 3.week e-mail
    Data 5.week e-mail
    Progress Report 1 10.week e-mail
    Progress Report 2 12.week e-mail
    First draft 14.week e-mail
    Final term paper 16.week portal
  • You need to send me your final decision on the topic of your term paper and send me the data that you’ll be using by the 5. Week of the semester. (This has to be done in writing). Not meeting this deadline will result in lowering of the weight of the term paper by 1 % point for each day by which you are late
  • You are also expected to give me an update on the progress of your term paper in 10.week and 12.week.
  • A first draft may be submitted to me on the 14.week. This, however, is optional and its only purpose is to give you feedback about potential improvements (if needed). No feedback will be provided if the draft is submitted after this week.
  • The term paper will be due on the 16. week. (Not meeting this deadline will result in a further lowering of the weight of the term paper by 2 percentage point for each day by which you are late (18% for one day, 16% for two days, etc.).
