QUESTION 1
Which tests have requirements about the nature or shape of the populations involved?
hypothesis
parametric
nonparametric
distribution-free
QUESTION 2
Which of the following is NOT an advantage of nonparametric methods?
Nonparametric methods can be applied to a wide variety of situations because they do not have the more rigid requirements of the corresponding parametric methods.
Nonparametric methods do not require normally distributed populations.
Nonparametric methods can often be applied to categorical data such as the genders of survey respondents.
Nonparametric methods are more efficient than parametric methods.
QUESTION 3
Which of the following is NOT true when using the sign test with data that are matched pairs?
Subtract each value of the second variable from the corresponding first variable.
Record only the sign of the difference when subtracting the value of the second variable from the corresponding value of the first variable.
Record ties with a positive sign when any matched pairs have both values that are equal.
Exclude ties and throw out any matched pairs in which both values are equal.
QUESTION 4
What do we call a nonparametric test that uses ranks of sample data consisting of matched pairs used to test for an association between two variables?
rank correlation test
Wilcoxon signed-rank test
Wilcoxon Rank-Sum test
Kruscal-Wallis test
QUESTION 5
Which of the following is NOT a key component of the rank correlation test?
The paired data are a simple random sample.
An alternative hypothesis for the rank correlation test is that there is a correlation between the two variables.
There is a requirement that any population has a normal distribution.
There is no requirement that the sample pairs of data have a bivariate normal distribution.
QUESTION 6
What do we call a number assigned to an individual sample item according to its order in a sorted list?
position
rank
placement score
sort
QUESTION 7
Which of the following is NOT appropriate for applying the sign test procedure?
Claims about several independent samples
Claims about the median of a population
Claims involving nominal data
Claims about data consisting of matched pairs
hypothesis
parametric
nonparametric
distribution-free
Explanation / Answer
1. A parametric method – Consider using when:
A nonparametric method – Consider using if the data is:
Hence Answer is Parametric
