Description
### Features of this statistics app ###
1. By using Stats tester plus, you can perform some statistics tests with an easy operation.
2. In the ver3.0 update, easy-to-understand explanations of statistics test methods have been added to HELP for each test.
3. Since one sample group (multiple data) is entered in one window, it is easy to enter, add, and modify many data.
4. In statistics tests that process raw data , the maximum number of data (max N) is 100 per one group). The maximum input frequency for Fisher's exact test is up to 1,000,000.
5. A built-in 10-keypad in a phone or calculator layout makes data entry easy. The iPhone standard keyboard can also be used.
6. From ver 2.0, except for a few test, one-tailed tests are supported in addition to two-tailed tests.
7. Input data and all output screen can be recorded by sharing (mail, memo). No need to take notes on paper.
8. 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 Mac, simply copy and paste your Numbers data into the input window of this app.)
9. 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. Its usability is the same as Stats tester plus. This developer hopes you confirm the usability with Stats tester mini.
## 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.

What’s New
Version 3.2.1
Ver 3.2.1
Wilcoxon signed rank test: Fixed a bug when test statistic (Ro) = critical value (R).
Ver 3.2
1. Bonferroni multiple t-test, Kruskal-Wallis test : The screen display of the results was improved.
2. Spearman rank correlation test, Wilcoxon signed rank test: Although the final p-value was correct, the intermediate results were sometimes displayed differently. So this issue was corrected.
3. X2 test (Goodness of fit) : Added explanation to the result and graph.
4. Others: Minor improvements were made to the screen display.
