Analyze whether the relationship between two categorical variables is significant .

 

How-To-Use:

The front node of this node needs to have the output of the data set.

 

Precautions:

[Category A] Only one column can be selected.

[Category B] Only one column can be selected.

❖Configuration

After adding the Chi-square Test node to the experiment, you can set the Chi-square Test node through the "Configuration" page on the right.

[Whether to enable Yates continuity correction] true is enabled; false is not enabled. The purpose of the correction is to reduce the error in the process of approximating discrete frequency data to the continuous chi-square statistic in the case of small samples.

[Category A] Chi-square test category column, only one column can be selected.

[Category B] Chi-square test category column, only one column can be selected.
