Dichotomization of Multilevel Variables to Detect Hidden Associations

open access: yesApplied Sciences, 2022
A test of independence is commonly used to determine differences (or associations) between samples in a nominal level measurement. Fisher’s exact test and Chi-square test are two of the most widely applied tests of independence used in the data analyses ...
