Biostatistics requirements, Dentistry

Aim of the course

The aim of the subject is to give an introduction to biostatistical methods, which can be used in different braches of medicine to solve biostatistical problems and to evaluate experimental results. In addition to providing a solid thoeretical foundation the course will also introduce the students to the art and science of performing the simplest calculations.

Short description of the course

Brief introduction to the most basic concepts of calculus (slop, fitting, area under the curve); counting techniques; descriptive statistics; algebra of events; probability; random variables; statistical distributions and their properties; binomial, Poisson and normal distributions; sampling techniques and characterization of samples; statistical test (z, t, F and chi2 tests)

Attendance
Conditions for signing the lecture book    Signing of the lecture book is denied if there are more than 2 absences from groupwise seminars.

Self control test
Students will write a grade-offering course test between weeks 12-14. The structure of this test will be identical to that of the final exam.

Exam
Students will write a grade-offering course test between weeks 12-14. The structure of this test will be identical to that of the final exam.

Final grade

Evaluation of the grade-offering test and the final exam is identical. - If the score of part A is less than 75% (30 out of 40 points), the student fails the grade-offering test or the final exam. Bonus points for lecture attendance are not added to the result of part A. If a student passes part A (i.e. the score is larger than or equal to 75%) on an exam or the grade-offering course test, the result is valid for his/her subsequent exam chances, i.e. it does not have to be retaken. - If the result of part A is less than 75%, part B is not evaluated (except for a C chance exam). If the student passes part A, bonus points (10p) for lecture attendance are added to the score of part B (max 100p) resulting in a final score (max 110p), which does not contain the score of part A. Based on this final score  the following grades are offered:

  • FS<55 fail
  • 55≤FS<65 pass
  • 65≤FS<75 satisfactory.
  • 75≤FS<85 good
  •  85≤FS excellent

A grade of 2 or better achieved on the grade-offering test is valid for the final exam. The bonus points for lecture attendance and the exemption from retaking part A of the exam are only valid for the course in which they have been achieved, i.e. they are not valid for repeated courses or exam courses. Rules for C-chance exams If the result of the written part of a C-chance exam is at least a pass (2) according to the rules pertaining to A- and B-chance exams, the grade of the C-chance exam will be what is to be offered based on the rules of the A- and B-chance exams. Part B of the written part of a C-chance exam will be scored even if the score of part A is less than 75%. If the result of a C-chance exam is a fail (the score of part A is less than 75% or the grade of part B with the bonus points is a fail), the written part will be followed by an oral exam. In this case the grade of the C-chance exam will be determined by the result of the written test and the performance on the oral exam.

Exemptions

Requests for exemptions from the biostatistics course have to be turned in to the Credit Transfer Committee. Such requests cannot be directly turned in to the Biomathematics Division or the Department of Biophysics and Cell Biology.

Information for repeaters

Credits achieved in a semester cannot be transfered to other semesters. Therefore, students repeating the course are subject to the same rules and requirements as those taking the course for the first time.

Rules for calculator

Rules for calculator usage during course tests and the final examination In order to ensure a fair evaluation, to avoid disturbances in the testing room, and to protect the security of the test material the following types of calculators are NOT permitted: - calculators with built-in computer algebra systems (capable of simplifying algebraic expressions) - pocket organizers, handheld or laptop computers - any device capable of storing text. Calculators with a typewriter keypad (so-called QWERTY devices), electronic writing pads and pen-input devices are not allowed either. Calculators with letters on the keys (e.g. for entering hexadecimal numbers or variable names) are permitted as long as the keys are not arranged in QWERTY format. - calculators or other devices capable of communicating with other devices - calculators built into wireless phones - calculators with paper tape or models that make noise In general, students may use any four-function, scientific or graphing calculator except as specified above. Sharing calculators during tests is not allowed, and the test proctor will not provide a calculator.
