Important Non-Parametric MCQS 1

The post is about Non-Parametric MCQs (Multiple Choice Questions) from Statistical Inference for the preparation of exams and different statistical job tests in Government/ Semi-Government or Private Organization sectors. The Quiz Non-Parametric MCQs are also helpful in getting admission to different colleges and Universities.

MCQs about non-Parametric Statistics

1. The sign test assumes that the samples are

2. The Wilcoxon signed rank is used

3. Three brands of coffee are rated for taste on a scale of 1 to 10. Six persons are asked to rate each brand so that there is a total of 18 observations. The appropriate test to determine if three brands taste equally good is

4. Which of the following tests is most likely assessing the null hypothesis of “the number of violations per apartment in the population of all city apartments is binomially distributed with a probability of success in any one trial of $P=0.4” 5. The Wilcoxon rank-sum test compares 6. To perform a run test for randomness the data must be 7. In a Wilcoxon rank-sum test 8. The Runs test results in rejecting the null hypothesis of randomness when: 9. In the Kruskal-Wallis test of$k$samples, the appropriate number of degrees of freedom is 10. Which of the following tests must be two-sided? 11. When testing for randomness, we can use 12. When using the Sign test, if two scores are tied, then we 13. The Mann-Whitney U test is preferred to a t-test when 14. In testing for the difference between two populations, it is possible to use 15. Comparing the times-to-failure of radar transponders made by firms A, B, and C, based on an airline’s sample experience with the three types of instruments, one may well call for: 16. The nonparametric equivalent of an unpaired samples t-test is 17. The Spearman rank-correlation test requires that the 18. If a Chi-square goodness of fit test has 6 categories and an N=30, then the correct number of degrees of freedom is 19. The Wilcoxon rank-sum test can be 20. Compare to parametric methods, the nonparametric methods are 21. Which of the following test use rank sums? 22.
