Design of Experiments (DOE)

Think you know your multiple comparison tests? Take this Experimental Design Quiz to assess your understanding of Tukey’s Test, Scheffé’s Test, Fisher’s LSD Test, Duncan’s Multiple Range Test, Dunnett’s Test, and Stepwise Multiple Comparisons.

These post-hoc tests are essential in ANOVA to identify significant differences between treatment means while controlling Type I error. Whether you are a statistics student, researcher, or data analyst, this Experimental Design Quiz will challenge your grasp of treatment comparisons, statistical significance, and hypothesis testing.

Topics Covered in this Experimental Design Quiz are:

• Tukey’s HSD Test
• Scheffé’s Method
• Fisher’s Least Significant Difference (LSD) Test
• Duncan’s Multiple Range Test
• Dunnett’s Test for Control Comparisons
• Stepwise Multiple Comparison Procedures
