Choose the correct answer from the statements indicated below: Chi square test is parametric Non-parametric test assumes normal distribution Results can be significantly affected by outliers in a parametric test Non-parametric test is more powerful as compared to parametric test 4.Select the option that represent the correct combination of non parametric tests and its equivalent parametric test repectively that can be used to compare two or more groups Wilcoxon Rank Sum Tests and Paired t test Wilcoxon Rank Sum Tests and Spearman correleation Spearman correleation and Krukal Wallis test Mann-Whitney U test and Pearson correlation 5.The use of Kruskal wallis test is most appropriate in which of these cases? These are more than two groups and each group is normally distributed These are more than two groups and the distribution in each group is nor normal These are two groups and each group is normally distributed These are two groups and the the distribution in each group is not normal) Score = Correct answers: Practice more: Practice Test on Cell Biology Methods in Biology Tags: Life Science Practice Test methods in biology Facebook Twitter
