Mathematical statistics are fundamental knowledge essential to understand or to estimate the data collected from various fields. At the beginning of this course, the student will study descriptive statistics so as to understand the characteristics of statistical data. Then, in order to prepare the learning of inference statistics, students will study basic probability theories, concepts of probability distributions, several discrete probability distributions, the concepts of continuous probability distributions and various important distributions for mathematical statistics. Finally, the students will learn the inferences and tests for the first step for the inference statistics.

This subject corresponds to the diploma policy DP1.

According to the diploma policy DP1, students will obtain knowledge of the mathematics as a basic major subject for common basic academic skills, and obtain knowledge of the mathematics necessary to obtain the School Teacher's License for mathematics.

In details, students will be able to explain and calculate the number of cases, the concepts of discrete and continuous probability distributions, and the inferences and tests to obtain basic mathematical statistics.

Those who attend 10 or more lectures out of all 15 lectures will be given the qualifications of the regular examinations. The overall grade of this course will be decided based on the sum of total 100 points of the midterm exam (40 points), the final exam (40 points), and the score of exercises (20 points), and those whose grade is 60 or more will pass.

The score of exercises will be proportional to the number of the passed exercises submitted before each due date, and the maximum score of exercises is 20.

For feedback, the answer of the exercise will be explained right after the submission, and the exercise will be corrected and returned in the offered session. Each due date of the exercise is the date of the next class. No delay of submitting the exercises are allowed.

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 exercises open to LMS (about 2.0 hour). If the content is hard for you, you can think about it together with other participants. Do not hesitate to ask the teacher in charge.

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 this course, you should analyze actual data with spread sheet software.

Refer to "Introductory Statistics" in 4. References, that is an open resource for university education for self-learning materials, to compare Japanese and English expressions for statistics.

Students must prepare a scientific calculator without a communication function for doing the exercises and the regular examinations.

LMS will be used for this course.
