## Resource summary

### Question 1

Question
Assuming the data meets the assumptions of parametric tests, non-parametric tests compared to their parametric counterparts ____________.
• Are more conservative
• Have less statistical power
• Are less likely to accept the alternative hypothesis
• All of the above

### Question 2

Question
A researcher measured leadership skills in doctors, police officers and accountants. The data were skewed. What is the most appropriate test to analyse the data?
• Kruskal-wallis test
• Friedman test
• Wilcoxon test
• Mann-whitney test

### Question 3

Question
The results of the test used to analyze the data described in question 2 showed a significant result. How should the researcher carry out post-hoc tests?
• Compare groups using Mann-whitney test
• Compare groups using Wilcoxon test
• Compare groups using t-Test
• Non of the above. Post-hoc analyses can not be carried out with non-parametric data

### Question 4

Question
An advantage of non parametric statistics is that ____________.
• They are easy to calculate
• They are very powerful
• You need a computer to calculate them
• They have many assumptions to meet

### Question 5

Question
Which of the following tests is analogous to a standard within-subjects ANOVA?
• Friedman
• Kruskal-wallis
• Wilcoxon
• Mann-whitney

### Question 6

Question
Tied scores (when two or more scores have the same value) may present a problem in non-parametric tests. The way to deal with them in a Kruskal-Wallis test is to
• Throw out the tied data
• Assign any tied values the lower of the ranks they would have recieved had they not been tied
• Use a random number table to assign ranks to the tied values
• Assign any tied values the average of the ranks they would have recieved had they not been tied

### Question 7

Question
A data-set contains the following values: 23, 28, 37, 23, 45, 49, 37, 62. Rank the values. Which rank is associated with value 37?
• 4
• 4.5
• 3.5
• 6

### Question 8

Question
Researchers wanted to examine whether the 'sea-food' diet was effective. A group of volunteers were placed on the diet and their weight (in kilograms) was measured at the beginning of the diet, after 1 month, after 2 months, then at the end of the diet after 3 months. The data were not normally distributed. Which test would be appropriate to analyse the data?
• Friedman
• Wilcoxon
• Kruskal-Wallis
• Mann-Whitney

### Question 9

Question
The output from the study described in question 8 is shown below. What is the correct way to report these results?
• The weight of the participants did not significantly change during the diet, x2 (3) = .60, p = .89
• The weight of the participants did significantly changed during the diet, x2 (3) = .60, p > .05
• The weight of the participants did not significantly change during the diet, x2 (3) = .60, p = .90
• The weight of the participants did significantly changed during the diet, x2 (3) = .60, p < .05

### Question 10

Question
In a Kruskal-Wallis test, the ____________ the value of H, the more likely you are to reject the null hypothesis
• More negative
• Smaller
• Larger
• H is not relevant for the Kruskal-Wallis test
