Through this simulation I chose to use the two-way ANOVA and nonparametric test to help me evaluate the effects of the diverse factors on two response variables‚ which were productivity and client satisfaction. My findings helped me to narrow down and identify the areas that needed most improvement. Three Lessons Learned

difference between some measures of central tendency (X bar) and its population parameter (μ). A number of tests may be appropriate in this situation‚ i.e. Parametric test and Non-parametric test. Parametric Tests Parametric tests are more powerful because their data are derived from interval and ratio measurements. Assumptions for parametric tests include the following: • The observations must be independent. • The observations should be drawn from normally distributed populations. • These
