## Using Storage ##
- An internal storage is used to store the input data. Tapping [Calc button] performs calculation in each statistical test, and the input data are saved until the next tapping. As the data are saved in the memory that can be accessed only with this app (Stats tester), other apps can not use the data. The data can be erased with the [All Clear] button in the option menu.
