The truth is that the chi square test will tell you the information depending on how you divide your data. One of the most important things that you need to pay attention to is on how you are building the different categories.

Besides, since the chi square test doesn’t handle percentages either, by dividing a class of 54 into groups according to whether they attended class and whether they passed the exam, you might construct a data set like this: So, one of the things that you can do is to create two categories – “Pass” and “Fail”. Since exams usually use test scores between 0 and 100, you can’t use this data as it is with a chi square test since these are numerical variables. Let’s say that you want to test whether attending classes has any influence on how students perform on an exam. The Chi Square Test – A Practical Example Make sure to confirm your results with our chi square calculator. Notice that the chi square test can’t be run with continuous or paramedic data such as weight in pounds, for example. This means that you will need to count the data and divided it into categories. One of the things that you need to know about the chi square test is that it only analyzes categorical data. Make sure that you use the chi square formula to determine the chi square value. This is also called a goodness of fit statistic since it measures how well the observed data actually fits with the distribution that you expect to see if the variables are independent. The Chi square test should be run when you want to test how likely it is that an observed distribution is motivated by chance.
