## Important information for Samsung users ##On some Samsung Galaxy models, there may be no space or comma key on the numeric keyboard. In that case, please install the Google Keyboard (Gboard) from the Play Store and try it as the default keyboard. This will allow you to use the Google numeric keyboard. This also solves similar problems in other calculation apps.

### How to use ###
## Data entry ##
1. You can put data into the input-window by using a keyboard or by pasting data from this app or other apps.
2. Since one input-window accepts entering of many numbers, it is easy to edit entered data.
3. When entering a lot of data, it is convenient to paste data from Google Sheets, etc.
## Sharing data and results ##
1. [Input-window] has own copy/paste functions.
2. Input and Result data can be sent to mailers or saved to clouds (Google Drive, OneNote etc) by [Share] button.
3. Data on the output-window can be copied to your device by [Copy Results to ClipBoard] button.
## Saving graph ##
1. Please use the screenshot function of your device.
## Others ##
1. Entered data and results calculated by each method are memorized until the next use. This function is a feature of this app and it is very convenient. [All Clear] button of option-menu(3 dot) on the first screen erases all saved data.)
2. This app can be used for basic statistics, biostatistics and medical statistics, etc. It can be also used to study statistical method by using textbooks or WEB pages.
