Condition for signature: participation on at least 75 % of the practices, the result of both midterm tests should be at least 2.
The midterm tests will be during the practice on the 6th and 11th weeks.
After the semester there is semifinal exam (written test)
We give possibility to practice statistics by excel on Wednesdays between 6:30 p.m. and 8:00 p.m. in the students laboratory of the department.
A tantárgy rövid leírása
The medically relevant elements of biomathematics, information theory, biostatistics and bioinformatics are discussed within the subject. During the practices done by computers the statistical tests, biological and medical databases are shown.

1. Statistics exams begin at 2:00 pm. Place: Basic Medical Science Center ("EOK" in Tűzoltó utca 37–47.), first floor, corridor "B" (the labs where you had your statistics and biophysics practices as well). Please arrive at 1:45 pm and wait in front of the corridor so we can begin the exam on time. Please keep in mind, that you may only leave the room if you finish your exam (upload your exam file).
2. Examinees will be informed about the room where they will write the exam on the spot. When your examiner calls, follow him/her to the room.
3. For the exam, we ask you to bring a personal identification document with photograph (e.g. personal identity card, passport, driving licence, residence card). Other cards (bank cards with photo, student card and the like) will not be accepted for identification. Everything else (coats, bags, food, drink, etc.) should be put in the locker. Cell phones should be switched off and put on the teacher's desk.
4. Examinees – after checking proof of identity – take place according to the instructions of the examiner.
5. Examinees download and – when the exam is over – upload the exam file according to the instructions of the examiner.
6. The exam file consists of calculation tasks and multiple choice questions (MCQs). An MCQ has only one correct answer option. Incorrect MCQ solutions receive negative marking. Unanswered questions receive zero marking.
7. The time available for completing the exam is 75 minutes. You may only leave the room earlier if you finish your exam (upload your exam file).
8. During the exam you may only use the computer and the electronic formula collection provided by us.
9. Exam files are corrected right after the exam. After the exams are corrected, results are announced on the spot. Then, you may look at your corrected exam as well. You have to reach at least 50% to pass the exam.
10. During the exam, using anything not provided by us; talking; and even the mere possession of cell phones or other electronic devices is strictly prohibited. Infringement of these rules as well as any other means of cheating will automatically result in
(i) immediate exclusion from the exam,
(ii) an "unsatisfactory" (1) grade,
(iii) and initiation of a disciplinary procedure.
Consultations during the Exam Period
Biostatistics consultations in the exam period will be on the following days at 4 p.m.:
Dec. 16, 27, 30, Jan. 6, 13, 20.
Before the first exam day we organize consultation in statistics on Dec. 9. at 2 p.m.
