Course Syllabus


The course focuses on practical application of data analysis methods and tools. All classes are conducted in a computer lab and include a brief review of the necessary theoretical principles, their software implementations as well as examples of application. In this class the R statistical programming language is used combined with a modern package ecosystem for efficient data analysis. The class is taught in blended learning mode. MOOC “Data Analysis with R” on the Udacity platform is incorporated into the syllabus. The MOOC is developed by Facebook.

Assessment Elements

Assessment Elements

  • non-blocking Participation
    Solving in-class and homework assignments. Participating discussions.
  • non-blocking Assessment
    Individual assignments on exploratory data analysis, time series forecasting and regression.
  • non-blocking Presentation
    A 7-10 minutes presentation on the business cases for using data analysis and predictive modeling in business and research.
  • blocking Final Examination
    Examination format: This is an oral examination: project presentation and defense (15 slides presentation). The computer application and written report must be submitted beforehand. Your teacher will provide instructions on how to submit. The platform: The exam is taken on Zoom or MS Teams platforms. Your lecturer will choose a suitable platform and provide the connection link for the examination. Students are required to join a session 15 minutes before the beginning. The computers must meet the following technical requirements: For MS Teams: https://docs.microsoft.com/ru-ru/microsoftteams/hardware-requirements-for-the-teams-app For Zoom: https://support.zoom.us/hc/ru/articles/201362023-System-Requirements-for-PC-Mac-and-Linux A student is supposed to follow the requirements below: Check your computer for compliance with technical requirements no later than 7 days before the exam; Sign in with your corporate account (@edu.hse.ru) and use your real name when connecting; Check your microphone, speakers or headphones, webcam, Internet connection (we recommend using wired Internet connection if possible); Close applications other that MS Teams/Zoom client software and the applications required to present your project. If one of the necessary requirements for participation in the exam cannot be met, a student is obliged to inform a professor and a manager of a program 2 weeks before the exam date to decide on the student's participation in the exams. Students are *not* allowed to: Turn off the video camera during the presentation of your team’s project. All team participants must enable video from the webcam while presenting. You can turn off the camera when your team is not delivering the presentation. Read a pre-made text during the presentation; Leave the place where the exam is taken (go beyond the camera's visible area) while your team is presenting; Students are allowed to: Ask questions to the presenting team. Interact with other team members while presenting your project. Connection failures: A short-term communication failure during the exam is considered to be the loss of a student's network connection with the Zoom or MS Teams platform for no longer than 1 minute. A long-term communication failure during the exam is considered to be the loss of a student's network connection with the Zoom or MS Teams platform for longer than 1 minute. A student cannot continue to participate in the exam, if there is a long-term communication failure appeared. The retake procedure is similar to the exam procedure. In case of long-term communication failure during the examination task, the student must notify the teacher, record the fact of loss of connection with the platform (screenshot, a response from the Internet provider). Then contact the manager of a program with an explanatory note about the incident to decide on retaking the exam.
