楽しい統計学 on Windows Pc

It is a completely free app that even beginners can easily learn statistics.
Focusing on the way of thinking and the flow of the story of statistics, I try to give a polite explanation so as to eliminate misunderstandings about statistics as much as possible.
I am trying to understand even the knowledge of mathematics in the second grade of junior high school.
Additional math knowledge required is explained in the app.
The app will advertise, but there is no internal charge.

[Main configuration of the app]
The app has a "learning" page, a "problem" page, and other related pages.

・ "Learning" page
On the "Learning" page, each item is explained for each field such as descriptive statistics and inference statistics.
You can check the pages you understand.

・ "Problem" page
On the "Problems" page, you can solve confirmation questions. Checks will be added to the correct questions.
On the "Problem" page, you can choose from the following two types to solve the problem.
・ Solve the problem from the list by field
・ Solve problems randomly on the comprehensive test page

・ Other related pages
You can also check the progress and achievement of learning on the "My Data" page.
In addition, recommended reference books are introduced in "Reference Books".

On the "Settings" page, you can set the sound and check the information of the app.
You can also remove ads for a period of time.

[How to remove advertisements]
If you watch a video ad from the "Settings" page, you can remove the ad on each page for a certain period of time.
Please try.

[Assumed user of the application]
People who say "I'm interested in statistics but a math book seems to be difficult" or "I want to know the atmosphere because I can roughly sketch statistics"
I would be happy if you could use it for people who say, "I started learning statistics, but I can't understand it only with mathematical formulas."

[Contents handled by the app]
This app mainly deals with the contents of "descriptive statistics" and "inference statistics".
・ Descriptive statistics
"Descriptive statistics" includes scatter charts, histograms, bar charts, pie charts, box plots, and other graphs.
Describes indicators such as mean, variance, kurtosis, skewness, five-number summary, and tables such as crosstabulation.
・ Statistical inference
"Statistical inference" focuses on the overall flow and way of thinking about frequency theory.
Describes probabilities, random variables, statistical models, point estimation, interval estimation, statistical hypothesis testing, and model evaluation.
We rarely deal with Bayesian statistics, and introduce individual probability distributions and statistical methods.
We do not rigorously define probabilities or prove the theorems.
Also, it does not explain the method using simulation.

[About defects, typographical errors, and mistakes]
We would appreciate it if you could contact us if you have any problems with the app or any mistakes in the content.
We will respond as soon as possible.

[App evaluation and opinions]
If you're happy with it, I'd be very happy if you could rate it in the store.
We would be grateful if you could feel free to contact us with your opinions and requests.
