The goal is to master the elements of mathematical statistics. In particular, we aim to understand descriptive statistics, basic probability theories, concepts of probability distributions, various discrete probability distributions and concepts of continuous probability distributions, various distributions and inferences and tests for the first step for the inference statistics. This subject corresponds to the diploma policies DP1.

Mathematical statistics are fundamental knowledge essential to understand or to estimate the data collected from various fields. The students will understand the fundamentals of mathematical statistics and will be able to calculate basic statistical calculation actually.

Passing the two reports is just the requirement of qualifications of the final examination. The overall grade of this course will be decided based on the final examination. If the result of the final examination is 60 or more, you will pass.

If you have ability to pass the two reports and to answer questions in a written exam similar to the two reports, you can pass this course easily.

For feedback, submitted reports will be corrected.

For preparations of each class, students must read and organize the contents, and must go through the example questions in the relevant part of the textbook (about 1.0 hour).

For reviews of each class, students must do the corresponding exercises on the textbook and reports (about 2.0 hour).

If you have any questions about the exercises, you should read the relevant part of the textbook carefully to solve the problems. If there is something that you can not understand, you should refer to the reference books.

This course handles the fundamental aspects of probability. Therefore, if you are not good at probability, you should review the probability at senior high school carefully. Furthermore, calculus will be applied in the latter half of this course. Therefore, you should review calculus carefully. During studying this course, you should analyze actual data with spread sheet software.

LMS will be used for this course.
