Exam 16: Nonparametric Statistics

A researcher examined the relationship between gender and attitudes toward drinking alcohol.The researcher obtained the following data: What is the rank sum for group 1?

Friedman analysis of variance by ranks is the nonparametric counterpart of one-way repeated measures analysis of variance.

The nonparametric tests presented in the chapter are based on rank scores,which is the equivalent to the ____________________ level of measurement.

The _____ involves using the Wilcoxon rank sum test or the Mann-Whitney U test to compare the mean ranks for all possible pairs of conditions.

The null and aternative hypotheses for the Wilcoxon rank sun test/Mann-Whitney U test are identical to those for the independent groups t test,except that they are stated in terms of the mean ranks.

Similar to the analysis of a Pearson correlation,the nature of the relationship when using a Spearman correlation is indicated by the sign of the correlation coefficient.

Rather than comparing groups in terms of _____,the nonparametric procedures compare groups in terms of _____ or other features of a distribution.

Which of the following nonparametric tests involves the analysis of ranked difference scores?

When ranking scores,what should be done in the case of a tie? (i.e.,two scores that are the same.

Under what conditions are the Wilcoxon rank sum test and the Mann-Whitney U test used to analyze the relationship between two variables?

The rank transformation approach involves

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

If one wants to compare the rank ordering of scores as a function of different groups,then a(n)_____ should be used.

The nonparametric counterpart to the independent groups t test is the ____________________ test.

There are two major types of nonparametric tests -- rank tests and sign tests.
