Description

### Features of this statistics app ###
1. By using Stats tester plus, you can perform some parametric and nonparametric statistics tests with an easy operation.
2. Since one sample group (multiple data) is entered in one window, it is easy to enter, add, and modify many data.
3. For tests with multiple input windows, 100 data can be entered for each input window. For tests such as chi-square test (2X2, mXn) and Fisher exact test (2X2), you can enter up to frequency of 100,000,000
4. A built-in 10-keypad in a phone or calculator layout makes data entry easy. Standard iPhone and Mac keyboards are also available, and these can be switched to a 10-keypad at any time.
5. Unlike the Mini version, Stats tester plus includes tests that allow not only two-tailed tests but also one-tailed tests. In addition, for tests that perform continuity correction, it is also possible to display the test results without continuity correction.
6. Input data and all output screen can be recorded by sharing (mail, memo). No need to take notes on paper.
7. Data can be imported into the input window from apps such as Excel and Numbers by copy/paste, although it takes a little time. When you have an M1~3 Mac, you can simply copy/paste Numbers data into the input window of this app.
8. You can check the usability of this app with Stats tester mini (free version). Stats tester mini has fewer tests than Stats tester plus and does not support one-tailed tests, but its usability is the same as Stats tester plus. Please download Stats tester mini and check the usability of this Plus version of Stats tester.
## how to use ##
Each test screen has [Help], [Example], [Graph], [Calc], [Clear] and [Share] buttons.
You can check the usage details in the free version of Stats tester mini.
