ANOVA in STATA || One-Way ANOVA & Kruskal-Wallis test in STATA || CRD and RBD ||Tutorial 6 of 4
This video tutorial illustrates how one can analyze three or more independent samples in STATA. The process involves importing dataset in STATA, viewing the structure of dataset, incorporating data manipulation, testing for normality assumption in STATA using QQ-Plot and Shapiro-Wilk test, analyzing the mean income levels among the countries using the parametric approach (One-Way ANOVA or Completely Randomized Design (CRD)) in STATA when normality assumption is satisfied, and analyzing the mean income levels among the countries using the nonparametric approach (Kruskal-Wallis test) in STATA when the normality assumption fails. The video tutorial also incorporated the Randomized Block Design (i.e. the two-way ANOVA with no interaction effects among the factors) for the parametric case and the Friedman test as the nonparametric alternative to the Randomized Block Design (RBD).
