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

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

For an experiment that includes four levels of the single independent variable with 4 levels and,4 different groups are compared,the most appropriate statistical test is the:

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.

A psychologist's is studying the affects of Ritalin on concentration in 40 children that have been matched on age and IQ.Twenty of the children receive Ritalin and are asked to take an exam that measures their concentration.The other 20 children did not receive Ritalin,but a placebo pill and took the same exam.What statistical test is appropriate for this study?

The calculation of eta²_____when the statistical test is not significant.

The appropriate statistical methods for Case III situations are techniques called logistic regression and polychotomous logistic regression.

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.

A Two-way ANOVA is used when there are two independent variables.

If you want to determine if GPA is correlated with SAT scores what test would you use?

Although the joint influence of two between-subjects independent variables on a dependent variable can be studied using two-way between-subjects analysis of variance,it is not possible to study the joint influence of two within-subjects independent variables.

In the example above if the researcher were able to reject the null hypothesis and state based on the color of the ice cream the ratings were different how would you determine the nature of the relationship?

The nature of the relationship in the independent groups t-test is determined by examining:

The inference of the relationship after using an Independent groups t-test is____________________.

An investigator should never focus on multiple parameters (means,medians,ranks).

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 distribution that you want to compare groups on.

Multiple regression involves two or more

Alternatives to the "null hypothesis testing approach" include:

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?

When both independent variables are within-subjects in nature,the data can be analyzed using a two-way repeated measures analysis of variance.

In the study above the independent variable is_____.
