For scientists, doctors, researchers and students, Bartlett Test App is a useful statistical tool for testing homogeneity of variances of more than two groups. If you want to compare the multiple averages of these groups, you need Bartlett test first. If the result is statistically significant (P value <0.05), Kruskal-Wallis test or Friedman test will be used for the comparison of the averages. If not-significant (P value ≥0.05), one-way analysis of variance (one-way ANOVA) test will be used.
This App will help your research work.
