Lesson 4G – Research Methods in Ergonomics

This lesson illustrates the most common parametric and nonparametric statistical tests used to determine whether interventions improve human factors and HMI issues in production systems environments.

Learning Objectives
  • Apply the 6-step method for solving statistical inference problems commonly encountered while measuring human performance for:  1) Two independent samples (Wilcoxon Rank Sum Test); 2) Two independent proportions (Chi-square Test for Proportions); 3) Paired samples (Wilcoxon Signed Rank Test); and, Three or more independent samples (Kruskal-Wallis Test)
