APPLYING ANOVA AND NONPARAMETRIC TESTS SIMULATION 2
In this week’s simulation, I chose the Kruskal-Wallis test. The three lessons learned
relative to ANOVA and Nonparametric Tests were the errors are random and independent of each
other, each population has a normal distribution, and all the populations have the same variance.
From the lessons learned through the ANOVA and Nonparametric Tests Simulation, I will be
able to apply the concepts and analytical tools learned at my workplace by applying ANOVA and
various Nonparametric tests to analyze the results of data for more efficient and effective
operations within my organization. Some of the suggestions that I made in the simulation for
month one were to conduct a Kruskal-Wallis Test, reject the null hypothesis, and provide training
for increase competency, which will help increase productivity of the software engineers of
Praxidike Systems.
For month two, I selected the type of project and scope changes as factors for analysis.
The correlation matrix showed that the factor “type of project” has a strong positive correlation
with the productivity of software engineers. The factor “scope changes,” on the other hand, has a
correlation coefficient of 0.6. It was difficult to make any definite conclusions from this number
as it was more than 0.5, but less than 0.75. Thus, further investigation of the factor is appropriate.
I also made suggestions to set competency levels for a project depending on the skill
requirements and to review project plans and account for scope changes at the planning stages.
For month three, I selected the number of defects as a factor of analysis. This factor has a
strong correlation with the variable client satisfaction. The other factors, on the other hand, have
correlation coefficients that are less than 0.5. This indicates that the factors do not have a strong
positive or strong negative correlation with client satisfaction. Thus, further investigation of the
factors is not necessary. I also chose two-way ANOVA to find out if there was any interaction
between schedule variance and number of defects. For example, a project that has a high number
