Nonparametric Tests And Chi-Square Analysis:
Questions And Answers
1. tests make assumptions about population parameters and the data is
assumed normally distributed, it is performed on numerical continuous or
ratio data.
Answer: Parametric tests
2. tests make no assumptions about population parameters and uses nom-
inal/ordinal data.
Answer: Nonparametric
3. data is ranked data
Answer: ordinal
4. data is categorical data
Answer: nominal
5. The corresponding parametric-nonparametric test for paired sample test is
, test
Answer: Wilcoxon Test
6. The corresponding parametric-nonparametric test for independent sam-
ples t-tests are the test
Answer: Mann-Whitney U Test
7. The corresponding parametric-nonparametric test for an ANOVA test is
test
Answer: Kruskal-Wallis Test
8. The corresponding parametric-nonparametric test for Pearson's r is
test
Answer: Spearman's rho
9. compares observed frequencies to expected frequencies. Provides sta-
tistical indicator for the statistical significance of the difference.
Answer: Chi-square
10. A chi-square critical region is always skewed
Answer: right-skewed
11. Determining df for chi square goodness of fit test
Answer: k-1 where k is the number of categories
