Exam 16: Nonparametric Statistics

The Kruskal-Wallis test is the nonparametric counterpart of one-way between subjects analysis of variance.

The Friedman analysis of variance by rank is a nonparametric alternative to which parametric test?

The _____ of the relationship for the Wilcoxon signed-rank test can be measured using the matched-pairs rank biserial correlation coefficient.

Which of the following research designs is appropriate for the Wilcoxon rank sum test?

Distribution-free tests are used when _____.

For the Wilcoxon signed-rank test,in order for the null hypothesis to be rejected,the observed value of T must be equal to or less than the critical value.

The nature of the relationship cannot be addressed in nonparametric tests.

The Spearman rank-order correlation is a nonparametric counterpart of the:

The most common approach to dealing with tied scores is to rank the scores,assign the tied scores the average of the ranks involved,and then to introduce a correction term into the formula for the test statistic to adjust for the presence of ties.

A researcher examined the relationship between gender and attitudes toward drinking alcohol.The researcher obtained the following data: What is the value for the Glass rank biserial correlation coefficient?

The null and alternative hypotheses for the Kruskal-Wallis test are identical to those for the one-way between subjects analysis of variance,except that they are stated in terms of the mean ranks.

Under what conditions is the Kruskal-Wallis test used to analyze the relationship between two variables?

The Friedman analysis of variance by ranks is typically used to analyze the relationship between two variables when:

The alternative hypothesis for the Kruskal-Wallis test can be interpreted as follows:

Two types of nonparametric tests are _____ and _____ tests.

The Wilcoxon rank sum test is not applicable when the sample sizes of both groups are 10 or greater.

Of the two major types of parametric tests,the ____________________ is used more often.

Rather than comparing groups in terms of means (as is the case with t tests and analysis of variance),the nonparametric procedures compare groups in terms of medians or other features of a distribution.

Statistical tests that require assumptions about the distribution of scores in the populations from which the samples are selected are called _____ statistical tests.

Another name for nonparametric statistical tests is a(n)_____.
