What algorithm does StatsIQ uses for Recommended Test?

We are a group of researchers and StatsIQ is very helpful to us specially with our colleagues in the academe. We just want to know how does Qualtrics StatsIQ know that a certain test is applicable or recommended? For us research professionals we can certainly know what test to do. However, we have encountered a test that StatsIQ recommended an ANOVA, however the test should be Chi-Squared Test. This will help us understand how StatsIQ runs the recommended test so we can share it to our colleagues.
