Exam 17: Overview and Extension: Statistical Tests for More Complex Designs

A nonparametric test should be pursued if there is a reason to believe that the _____ of the corresponding parametric test have been violated to the extent that the parametric test is not robust.

Dr.Jones found that there is a relationship between day time drowsiness and what time you wake up in the morning r(50)= .60,p<0.01.This relationship has a ____________________ correlation.

The use of Case II statistics is appropriate when a qualitative variable has many values and there are insufficient number of cases within each level to justify the analysis of means,medians,and the like.

If both variables are qualitative,but one or both are within-subjects in nature,the appropriate method of data analysis is the chi square test as discussed in Chapter 15..

Alternatives to the "null hypothesis testing approach" include:

The use of IPod's may induce hearing loss according to research conducted at Washington State University.They had a total of 500 subjects that were given IPods set a decibel (db)rate of either 0 (no sound),40db or 70db.After listening to the same music on the IPod's for 1 week each subject was given a hearing test.The two confounds that should be addressed are the mount of ____________________ prior to the study as well as the participants' ____________________.

In the example above it was found that the higher your GPA is the higher you scored on the SAT which indicates_____.

When both of the variables under study are quantitative and between-subjects in nature,the appropriate method of data analysis is the

If group means are the focus of an analysis where the independent variable is qualitative and the dependent variable is quantitative,which of the following are further considerations which must be given before the type of test is chosen?

A parametric procedure would not typically be used when a quantitative dependent variable has only two levels because the _____.

The Hotelling T² test is used when a multivariate analysis of variance is applied to

If ranks are the focus,then parametric methods should be pursued.

The goal of factor analysis is to determine if the correlations among a set of variables can be accounted for by one or more underlying dimensions,or factors.

Which of the following is not an important question when analyzing bivariate relationship?

Which of the following is used to examine relations among three or more qualitative variables simultaneously?

If the dependent variable is measured on an ordinal level that seriously departs from _____,then a nonparametric test might be pursued instead of a parametric test.

Given the information above,assume that the sample population was not normally distributed what statistical test would be appropriate?

If both variables are qualitative,but one or both are within-subjects in nature,_____ of the statistical tests we have considered can be used.

The major factor to be weighed when deciding whether to use a parametric or a nonparametric test is the decision about what aspect of the _____ you want to compare groups on.

If you set your alpha level at .01,nondirectional,and you are using a correlated t-test and have a total of 30 subjects what is your table or critical t ?
