Frequently asked questions

I have a question regarding the lecture?

Please ask your question in the discussion board of this course. Other students and myself can then try to help you.

The term has already started. Can I still join the course?

You have to settle the formalities with your examination office. I admit all students to the course, no matter when they join. However, when you join late you have missed some material and you have missed some of the homeworks. Since all parts of the course count (including the homework) you might want to start in the first week.

I realise I have not enough time for the course. How can I leave?

Please check: What would happen if you don't formally leave? For most degrees the number of exams you can take is limited, but not the number of courses. It may well be that it makes no difference whether you formally remain in the course or whether you formally leave.

If you want to leave and if you can't do this with Friedolin, you can ask your examination office (Prüfungsamt) for support. Alternatively you send me an email with a qualified electronic signature (so that I know that it is really you). To produce such a signature you need a user certificate.

Which questions should be asked in consultation hours?

Questions which don't refer to the lecture but only to you. These are questions regarding your study plan, letters of recommandation, etc. You want to prepare these questions with the help of an email.

I need a letter of recommendation.

Lecture, Exercises, Handout, Q+A session, Homework... - this is too much.

Please use those components you find helpful. There is substantial overlap among lecture, exercises and the handout. You don't miss anything if you learn with only a subset. In any case you do have to take the homework.

Do I have to take the homework in the same term as the exam?

Yes, homework and exam can not be spread over different terms.

How much time do I have for each homework?

There is no restriction. You can open the homework on Monday, you can work on it during the entire week and submit your answers on Sunday. The exam is different: There you have just one hour.

Is it possible to install R and RStudio on a network filesystem (e.g. Microsoft OneDrive)?

Theoretically this should be possible - however, there are a number of pitfalls (and few benefits). A local installation seems to be easier.

How should I enter decimal numbers in Moodle?

Unless stated otherwise, use three or more digits after the decimal point. A higher precision is possible but optional. Numbers in exponential format (1.579e-06) could either be rounded (0.000) or entered as 0.000001579.

Moodle complains about “incomplete answers”.

If you enter a number in a format Moodle does not understand, Moodle warns you. The format depends on your language settings. E.g. if your language setting is German, you enter numbers with a decimal comma (3,14). If your language setting is English, you enter numbers with a decimal point (3.14).

How does Moodle grade answers to the homework?

  • If the answer is a number, you get points for each correct answer (unless stated otherwise: 3 digits precision is enough). You get zero points for a wrong answer.
  • If the answer is a choice out of two, you get the points for a correct answer. You get zero points for no answer. You get negative points for a wrong answer. Moodle does this, since, with random answers, you get in expectation zero points, i.e. the same number of points you would get with no answers.

I could not submit the homework in time. Can I still get credits for my homework?

After the deadline for the submission, Moodle reveals the correct answers. This is, hopefully, useful for those students who did submit in time. With the correct answers available for everyone, submitting these answers no longer shows that you have understood the material. Therefore, late submissions aren't possible.

How hard is the exam?

Exam questions will be similar to homework questions.
