The Praxidike Systems corporation has identified opportunities with on-time actors line and customer satisfaction. Applying analysis of variance as well as other nonparametric sieves, such as the Kruskal-Wallis study, allows the company to locate the causes of the poor quality. In terminate the ?Applying ANOVA and Nonparametric Tests? simulation, I learned the following three lessons relation to the analysis:1.Accurately identifying a one-way analysis versus a two-part analysis is crucial to playacting the tests. 2.Use the Kruskal-Wallis test if un subject to determine if the selective information has a normal dispersion. 3.Be awargon of the three major a ssumptions and know if they argon met:?Errors are random and independent of steally other. ?Each people has a normal distribution? each(prenominal) the populations have the same variance. (Lind, Marchal, & adenylic acid; Wathen, 2004). A one-way analysis only looks at one variable such as client satisfaction. A two-party analysis compares two variables such as project complexness and employee competency. The variables are compared against the variances such as high, medium, and low.

Being able to separate the variables from the variances and not confusing them will ensure the test results are accurately considered. Also, knowing if the d ata has a normal distribution will determine! if ANOVA is used or if other nonparametric test is used. If the mortal is unsure, a nonparametric test such as the Kruskal-Wallis test should be used along with the chi square honor of fit test. After completing the simulation and being able to link the data analysis more realistically to the business organisation world, I could plan myself using ANOVA to compare productivity...
