Course description
Mathematical statistics is a tool of estimating the property of the population (a large set of data) from its small sample. In this course, we will first introduce basic concepts and terms of statistics such as means, variances, probability distributions, etc. Then, observing the connection between statistical properties of samples and those of the population, we will learn methods of interval estimation and hypothesis testing.

Takashi Yoguchi (a part-time lecturer) will be in charge of this course.
Expected Learning
The goal of this course is to be capable of
(1) understanding standard terms and notations of mathematical statistics,
(2) calculating the mean and standard deviation of a given set of numbers,
(3) applying normal distribution or Student's t-distribution to estimation of the mean of the population,
(4) testing a statistical hypothesis by using normal distribution.

Message from instructor(s)
It seems that leaners are likely to be embarrassed by some confusing terms (such as “mean of sample mean”). So, when a new word appears, please be aware of considering the meaning of it.
