Appendix: Choosing the Correct Statistic
Overview
This appendix gives a structured approach for choosing the correct statistical approach to use when analyzing data. The choice of a specific statistic is based on the number and scale of the response (dependent) variables in the study considered in conjunction with the number and scale of the predictor (independent) variables. Commonly used statistics are grouped into three tables based on the number of response and predictor variables in the analysis.
