Description

### Features of this app ###

1. By using Stats tester mini, you can perform some statistics tests and obtain graphs by an easy operation.
2. Since one sample group (multiple data) is entered in one window, it is very easy to enter or edit the data.
3. Unlike other test apps, not only final conclusions such as p-values, but also intermediate results are shown.
4. Input data and test results can be recorded by sharing (mail, memo). There is no need to make notes on paper.
5. You can import data by copy/paste from apps such as Excel, Numbers, memo, etc.
6. Numerical input is very easy with the built-In ten-keyboard (phone and calculator layouts).
7. This app has been fully verified to work with the M1 Mac. The M1 Mac makes it easy to work with other apps (Numbers, Excel etc.).

## how to use ##

Each test screen has [Help], [Example], [Graph], [Calc], [Clear] and [Share] Buttons.
On the "How to use this app" screen, details such as its features and specifications are written.

1.8.1
2020-09-08
Version 1.8.1 Update
Bug fix
In the previous version, [Shapiro-wilk test] crashed when inputting 100 data. This was fixed.

Version 1.8 Update
1. New statistics test
Added [Paired sample t-test].
2. Improvement (Linking with other apps has become easier.)
In the previous version, after tapping the [Calc] button, data was saved in iPhone only when the calc result could be output. From this new version, the input data is saved in iphone without pressing the [Calc] button.
Because of this feature, in the case of [Two-sample t-test], you can paste the column_A and column_B data of Numbers (iOs app) to the window_A and window_B of [2-Sample t-test], respectively. This means that you can easily enter up to 100 data/group to [Two-sample t-test] from the Numbers app by 2 copy/paste operations
3. Bug fix
a) [Two sample t-test], [one-sample t-test], and [correlation and regression]:
Fixed the case where the calculation cannot be done with specific data (eg, the same value).
b) Other minor corrections to the display.

1. New
Added [6. Shapiro-Wilk test (Normality)] and Normal probability plot graph.
2. Improvement
a) [Mean and SD, etc]: Calculation of Kurtosis (α4) was added. If α4 = 3, it means normal distribution.
b) [t-test (Student and Welch]: Welch's p-value was changed to the direct calculation from the interpolation method.
1.6
2019-09-23
1. Added support for Dark Mode on iOs 13.
