Greetings

This is Relaxed Statistics.
Let's learn statistics together!
The starting point is problems from the Statistics Grade 2 exam..
I aim to share information by using intuitive imagery to help statistics sink in smoothly.
I hope to run this site so that while you are having fun solving problems, you will find that you have gained knowledge before you know it.

Table of Contents

You can jump to each article from the "Table of Contents"!

Structure

The articles are structured in three parts: "Solving Problems," "Learning," and "Practicing.".

"Solving Problems" involves solving problems from the official problem collection.
I will try to make the content as intuitively understandable as possible.

"Learning" and "Practicing" will delve into "related themes" that extend from the problems!
You can enjoy these even if you don't have the official problem collection on hand.

"Learning" is a chapter thatwrites about basic statistical content related to the theme in a reading format. I will move away from rigid, textbook-like content and value intuition and impressions.
I will try to help you enjoy the flavor of statistics by using images such as charts and diagrams.


"Practicing" is a chapter where you canactually try out calculations and graph drawing!
I will provide sample code for Excel, Python, R, etc.
I aim to make statistics feel more accessible by utilizing these tools!

Textbooks

In the "Solving Problems" chapter, I will tackle problems from the "Statistics Grade 2 Official Problem Collection CBT Version"!
In the articles, I will refer to it as 📘 "Official Problem Collection".

I cannot reprint the problem statements, answers, or explanations from the official problem collection directly in the articles..
I hope you will keep the "first edition" of the official problem collection on hand when reading the articles.
Don't worry if you don't have the official problem collection!
Please enjoy the "Learning" and "Practicing" chapters as reading material and hands-on practice.

Reference Books

The Statistics Grade 2 exam serves as a benchmark for measuring "the degree of acquisition and understanding for the application of statistics at the university foundation level."
If you want to learn statistics at the university foundation level in depth, why not use the following reference books to train your foundational skills further?

📕 "Statistics Grade 2 Correspondence: Fundamentals of Statistics"
I will refer to this as the "Official Textbook" in the articles.
I plan to use the "Revised 15th Printing" to cite or reference sections from the official textbook within the articles.

📗 "Complete Self-Study: Introduction to Statistics"
This is a great book that explains the essence of statistics without using mathematical formulas.
It seems to be the first book many people choose when starting their study of statistics.

📗 "Introduction to Statistics"
This is an introductory book on statistics recommended for those with a solid mathematical foundation.
It is a bestseller affectionately known as the "Red Book."
