Please try to look at your data with a histogram.
The use of histograms makes it easy to see how the data is grouped and distributed, or whether there are outliers or abnormality. Only with numerical data, these are difficult to see.
[Home]
This is a display screen of the histogram.
It also displays the mean and standard deviation and others.
[New File]
You can make a new data file.
In the "Data?" Field, enter numerical data separated by a space.
Please enter 2 or more data.
If there is not more than one input, the data being displayed on the [Dosubump] screen just before will be copied.
Enter a file name for identification in the "File Name?" Field.
(If you do not enter it, the system will give a file name made from date and time.)
Click the "CSV" folder icon to switch to the file selection screen,
You can select a data file in CSV format.
("CSV" folder icon appears when "Option-*Use CSV data*" in the [Settings] screen is checked.)
If the numbers are separated by commas (,) or semicolons (;), check the appropriate characters in "Additional Delimiter".
When data entry is complete, click the "OK" button.
[My Data]
This is a selection screen of saved data file.
Touch the list to select the data file.
You can delete it by swiping.
[Edit]
This is a screen to edit data of the selected file.
Touch the data you want to modify, a new data input dialog will be displayed.
You can delete the data by swiping.
You can add data by clicking the "+" button.
(You can enter multiple data separated by a space.)
[Take a glance]
You can test how the histogram changes with the specified "sample size", "mean value" and "standard deviation".
Click the "OK" button to generate random data and draw a histogram.
(The larger the sample size, the longer it will take to calculate.
It is recommended to try at around 100,000 at most. )

+++++++++++++++++++++
We named this app "Dosubump".
It sounds like the word for "frequency distribution" in Japanese.
