/Class Outline Upon completion, students will have the knowledge and skills to:
1. Summarize and graph data appropriately
2. Work with random variables and probability distributions
3. Describe and use the normal distribution appropriately
4. Identify when and how to carry out basic statistical inference such as estimation and hypothesis testing
5. Identify contexts in which particular statistical methods may be inappropriate

2. Goals of descriptive statistics and key terminology
3. Describing univariate data
4. Numerical summaries for quantitative data
5. Describing bivariate data
6. Data collection and research design
7. Introducing probability: modeling uncertainty
8. Basic properties and calculation rules of probability (Homework 1 due)

12. Expectation, variance, transformations and sums of random variables
13. Joint, marginal, and conditional distributions
14. Modes of convergence: convergence in probability and in distribution
15. Review (Homework 2 due)

Grade for this course is determined by two homework assignments and a final exam. The course schedule is intended as a guideline; depending on the pace of the class and students’ understanding, some parts of the course content may be adjusted.

Learning techniques to be incorporated

Suggestions on
Preparation and
Review There are no prerequisites. It is recommended that students take the course Mathematical Economics concurrently. Students who wish to deepen their understanding of statistics are encouraged to take or audit courses related to statistics from other departments.

Requirements • This course is designed on the assumption that students are comfortable with probability and statistics at the high school level. We will review relevant mathematics when introducing new concepts, but students are encouraged to review relevant high school textbooks and the supplementary materials provided outside of class as necessary.
• University lectures move at a fast pace. If you can understand the lecture notes, attending every lecture is not required. However, if you find it difficult to keep up with the material, please take initiative in your learning by reviewing the material with classmates and working collaboratively to deepen your understanding.

Grading Method Homework assignments 1 & 2 combined: approximately 40%
Final exam: approximately 60%
N.B. weights on homework assignments and exam are subject to change.

Practical Experience

Summary of Practical Experience and Class Contents based on it

Message You may often hear terms such as data science, machine learning, and AI, which are transforming our everyday lives. Statistics provides the foundation for these fields. Because Statistics I and II focus on basic concepts, the importance of what you learn here and its connection to applications may not be immediately obvious. However, the material covered in this course forms the foundation for more advanced subjects you may take later, such as Econometrics. I encourage you to engage actively in the course and develop the ability to interpret and use data correctly.

We will occasionally conduct demonstrations of practical problems using the statistical software R. These exercises will not directly affect your course grade, but students who are interested in learning how to code or program are encouraged to bring a laptop computer.

Other Language of instruction: The course will be conducted primarily in Japanese. However, since some of the reference materials are written in English, technical terms may occasionally be presented in both Japanese and English.

Please fill in the class improvement questionnaire which is carried out on all classes.
Instructors will reflect on your feedback and utilize the information for improving their teaching.
