Explore the chi-squared test, a statistical method for analyzing contingency tables to assess the independence of two categorical variables in large samples.
Chi-square analysis is applied to categorical variables and is especially useful when those variables are nominal (where order doesn’t matter, like marital status or gender). Test of Independence When considering student gender and course choice, aχ2test for independence could be used. To do ...

Home›Statistics Guides›What is R Squared (R2)? Definition:R squared, also called coefficient of determination, is a statistical calculation that measures the degree of interrelation and dependence between two variables. In other words, it is a formula that determines how much a variable’s ...
The most common application of this method is sometimes referred to as linear or ordinary. It aims to create a straight line that minimizes thesum of squaresof the errors generated by the results of the associated equations, such as the squared residuals resulting from differences in the observed...
