Nonparametric Tests
Nonparametric test use these two kinds of data
What is nominal and/or ordinal data?
This type of ordinal data is used for the Wilcoxon Rank-Sum Test
What is a rank?
What is a two-group correlated-groups design?
The formula of the chi-squared test.
The sum of the observed - expected squared over the expected.
x2= Σ(O-E)2
______
E
The test does not use these types of parameters(range)
What is a population parameter?
This is another name for the Wilcoxon Rank-Sum Test
What is a signed rank test?
Wilcoxon Rank Sum Test is to ___ design, as Wilcoxon Matched-Pairs Signed Ranks T-Test is to __ design.
What is between subjects; within subjects?
The frequency that would be common knowledge or simple math
What is the expected frequency?
This type of central tendency is used to determine whether it is parametric or nonparametric
What is the median?
A Wilcoxon Signed-Rank Test compares :
A. two related samples
B. matched samples
C. All of the answer choices
D. repeated measurements that can determine if their ranks differ
C. All of the answer choices
Wilcoxon Matched-Pairs Signed Ranks T-Test looks at this type of observations
What is a dependent/related observations?
The frequency the problem gives you
What is the observed frequency?
A nonparametric test is:
A. Answers B and C
B. a distribution-free test, that does not assume your data follows a specific parameter
C. an analysis of nomianl/ordinal data
D. None of the above
A. B and C
Data for a Wilcoxon Rank Sum Test comes from here.
What is the same population?
The extension of the Wilcoxon Rank Sum Test for use with more than two groups is _____.
What is a Wilcoxon Matched-Pairs Signed Ranks T-Test?
True or False: A chi-squared test can not show the differences in what the researcher expects and what the researcher knows about the data
False, the test does show the difference
Three Types of Nonparametric Test
What are the Wilcoxon Rank-Sum Test, Wilcoxon Matched-Pairs Signed-Ranks T-Test, and Chi-squared
What is a t-test?
Wilcoxon Matched-Pairs Signed Ranks T-Test can look at studies __ and __.
What is before and after?
The chi-square test looks at this type of observation
What is an independent observation?
