This chapter serves as a navigation tool that informs the investigator on what statistical test to perform when the data are continuous, non-continuous, log-distributed, when one has time-to-event data, and it explains why these are proper tests. The reader may have to consult Chapter 1 again to look up data types and why it is important to know how their data are distributed, and particularly why it is important to harness this knowledge as they become more proficient in their statistical skills, so that they can comfortably assess what is proper or improper statistics when evaluating a manuscript for publication, or just to fully understand peer-reviewed methods. The chapter also provides numerous online tools that you may use free of charge, to conduct your own statistical tests.
