Sokan affiche le diagramme de dispersion et le coefficient de corrélation de vos données.
Is there a correlation between weight and height?
Also, is there between the latitude and average temperature?
You can see at a glance whether there is a correlation by plotting the data on a scatter plot.
For reference, the correlation coefficient is.
[Home]
This is a display screen of the scatter plot.
It also displays the correlation coefficient.
And you can check the histogram of each data by swiping the screen.
[New File]
You can make a new data file.
In the "Data?" Field, enter numerical data in the order of the horizontal axis (x-axis) and vertical axis (y-axis) separated by a space. (x1 y1 x2 y2 x3 y3 ....) (e.g. 2.3 2.0 -3.2 -2.5 4.0 4.2 .....)
Please input two or more data.
If there is not more than two input, the data being displayed on the [Home] 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 scatter plot changes with the specified "sample size" and "correlation coefficient".
Click the "OK" button to generate random data and draw a scatter plot.
(The larger the sample size, the longer it will take to calculate.
It is recommended to try at around 500 at most. )
