What is a chi-squared test?
The Pearson chi-squared test is a frequently used test in clinical research. It studies whether or not there is a statistical association between two variables. For example, it may find whether or not gender is associated with cardiovascular disease. The variables to be tested must be categorical.
Is a chi-squared test the same as Fisher’s exact test?
Both tests are used to find an association between two variables and are very frequently used in medical studies. However, their calculation methods are completely different. Due to its parametric nature, a Chi-squared test cannot be used in every circumstance. When using EasyMedStat, the most appropriate test will be chosen for you automatically, according to your data, so you do not have to worry if you can use the test or not. EasyMedStat does all the work for you.
