Exam 18: Overview and Extension: Statistical Tests for More Complex Designs

One example of a multivariate statistic is two-way between-subjects analysis of variance.

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.He calculates the strength of the relationship as ____________________.

A researcher is studying effect of gender on what type of car he or she buys.The researcher should use the ____________________ to analyze the data.

A researcher reported gave subjects 3 different doses of caffeine 0mg,50mg,100 mg and 150mg.She had a total of 90 subjects,30 in each group.After ingesting caffeine a recall test was used to assess their short-term memory.The researcher should use ____________________ to analyze the data.

Dr.James used a Pearson correlation and found that there was a relationship between the number of publications of faculty members and the number of graduate programs offered (r=.85).To determine the nature of the relationship what should Dr.James do?

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

Multivariate analysis of variance tests whether the groups have different population means on each of the dependent variables considered separately.

In situations involving the analysis of two or more dependent variables in a factorial design,analysts will often perform a multivariate analysis of variance.

A researcher is interested in whether the number of years working in a company (1,5,or 10)might have an effect on job satisfaction (rating scale 1-50),employer satisfaction (rating scale 1-20)and perception of job difficulty (rating scale 1-10).Which of the following tests would be used to analyze this data?

______ is the statistic used to indicate the strength of relationship between a criterion variable and several predictors in the context of a linear model

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

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 means are the focus,then a _____ test is usually the analysis of choice.

If means (or linear relationships)are the focus,then a nonparametric test is the analysis of choice.

The F test for a one-way repeated measures ANOVA is appropriate when the dependent variable is_____in nature and measured on a level that approximates_____level of measurement.

Compare and contrast Parametric and Nonparametric statistical tests.

When the independent variable is quantitative and the dependent variable is qualitative,an appropriate method of data analysis could be

Under the correct circumstances a nonparametric tests can be as powerful as a parametric test.

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.

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