 Interactive ChiSquare Independent Test The extension of contingency table is to test the null hypothesis that the two variables in the table are actually related (dependent) or not. The interactive program below will automatically compute the ChiSquare values from your raw data including the chisquare probability and interpret the result of the analysis. (Yes, this program is free to use. Just donate for further development if you feel delighted). To use the program, you need to copy and paste or type two lists of data. Each list indicates data of one variable data. The data item can be a number or a string. The two lists must have the same number of data. The lists of data are separated by comma (if you type a space, the program will automatically insert a comma for you). Then, click "Do Independent Test" button. The example given here is taken from the sample questionnaire of this tutorial variable “Activity Time in Parks” and variable “Mode to go to park”. Feel free to change the sample data with your own data. The outputs of the program are:
In the next section, you will learn different method to analyze your data using conditional probability, and Bayes Theorem. See also: Regression Tutorial, Learning from Data, Mean and Average
