Chi-Square Test The chi-square statistic is represented by χ2. The tests associated with this particular statistic are used when your variables are at the nominal and ordinal levels of measurement – that is, when your data is categorical. Briefly, chi-square tests provide a means of determining whether a set of observed frequencies deviate significantly from…
Machine Learning, Types and its Applications Machine learning is a subset of computer science that can be evaluated from “computational learning theory” in “Artificial intelligence”. By definition it is a “Field of study that gives computers the ability to learn without being explicitly programmed”. Machine learning mainly focuses in the study and construction of algorithms…
