The world is constantly curious about the Chi-Square tests application in machine learning and how it makes a difference. Feature selection is a critical topic in machine learning[1], as you will have multiple features in line and must choose the best ones to build the model. By examining the relationship between the elements, the chi-square test aids in the solution of feature selection[2] problems. In this tutorial, you will learn about the chi-square test and its application.
What Is a Chi-Square Test?The Chi-Square test is a statistical procedure for determining the difference between observed and expected data.[3] This test can also be used to determine whether it correlates to the categorical variables in our data. It helps to find out whether a difference between two categorical variables is due to chance or a relationship between them.
