İKT 253 : İstatistik / Statistics *** Announcements ***
The students who have missed a midterm (and have an accepted excuse) may take the make-up exam (telafi sınavı), which will be given right after the final exam. Please see the instructions for the final exam below, under the "Exams" heading. Stata: You can install it in your computers (please contact the IT -Bilgi-İşlem- department of the university). We recommend that you familiarize yourselves with this software that has a huge network of users. ****Attendance requirement****Students have to attend at least 30 hours of lecture time in the semester. Those who do not meet this requirement will receive a U grade.
The following students have received a U grade in the course. These students may not take the final exam: - Ahmet Han Ödemiş - Berkay Aydinç - Berkay Simit - Cem Karahanoğlu - Hasan Akhan Özbek - Nedimcan Zeydan - Yakup Karabay - Yusuf Ozan Kırlı Lecture hours for Fall 2019: Tuesdays 10.30-12.20 (Room 311) Fridays 08:30-10:20 (Room 177) Office Hours: By appointment.

Bayes' Theorem simplified:

Watch the videos in the following links to see where the Poisson distribution comes from:
https://www.khanacademy.org/math/statistics-probability/random-variables-stats-library/poisson-distribution/v/poisson-process-1 https://www.khanacademy.org/math/statistics-probability/random-variables-stats-library/poisson-distribution/v/poisson-process-2 For a random variable with a Poisson distribution, both the mean and the variance are equal to lambda. Note that this property is specific to the Poisson distribution and that it cannot be generalized to other distributions.
See below for an explanation of the relationship between Poisson and exponential distributions:
Note the new revised version of slides for Chapter 7.

TablesExamsThe final exam will consist of 4 questions and will be worth a total of 20 points.
There will be one question on the calculation of the mean and variance of a portfolio. There will be three questions on hypothesis testing, type I error, type II error, p-value, and power. (testing the mean, proportion, or variance of a population; or the equality of variances or equality of proportions.) Additional InformationSlides of the textbook are available at
