Praxidike Systems is a software company that is having trouble find why their escorts are not being completed on time. The scenario starts by presenting two non-parametric examination methods with include analysis of variance and Kruskal-Wallis. Non-parametric seeing methods have certain requirements to be utilized effectively. The major assumptions of ANOVA testing include the following: the population has a mean(prenominal) scattering, errors are independent, and each population has the same variance. The Kruskal-Wallis test, on the otherwise hand, does not require the assumption of a normal distribution and the data must be on an ordinal scale. This is typically a better option if all the assumptions of ANOVA cannot be met. The scenario provides three examples of how these testing methods can be applied to factual world situations.
During the first phase of the scenario I chose to apply the Kruskal-Wallis test because all the assumptions of ANOVA could not be met. After analyzing the data, it was unmixed that the level of competency of the software engineers was correlated with their productivity. In the scrap phase I decided to run the two-way ANOVA test that analyzed the difference between competency and project type.
The test provided 3 null hypotheses, which take to similar results to those in phase one. Last, these testing methods are used to analyze a situation in which a customer was unhappy because of a product defect. A two-way ANOVA test led to the conclusion that a defect tracking system should be in place to prevent future occurrences. An independent analysis of each group concluded that this would be the most effective solution.
Overall, my suggestion to the company is to provide further training to engineers because great competency leads to greater productivity. It would also be beneficial to watch a proposal for each project based on the level of competency needed. A well defined plan will help management more effectively...If you want to bilk a full essay, order it on our website: Ordercustompaper.com
