Exam 14: Making Use of Associations Tests

With associative analysis,the null hypothesis states there is no association(relationship)present in the population and the appropriate statistical test is applied to test this hypothesis.

It is important to note that the angle or the slope of an ellipse has everything to do with the size of the correlation coefficient.Everything hinges on the width of the ellipse.

When a researcher ________,but still believes some relationship exists between two variables,he or she may resort to running a scatter plot.

Presence refers to the finding that a systematic relationship exists between the two variables of interest in the population,but is not a statistical issue.

A relationship is a consistent and systematic linkage between the levels for two scale variables or between the labels for two ordinal variables.

Observed frequencies are compared to ________,which are defined as the theoretical frequencies that are derived from this hypothesis of no association between the two variables.

A monotonic relationship means the researcher knows the general direction(increasing or decreasing)of the relationship between two variables.

Some associative analysis statistics,such as correlations,may not indicate the strength of the relationship in a straightforward manner-that is,just by their absolute size.

A relationship which is described as one in which there is a low probability that two variables will exhibit a dependable relationship is referred to as:

There are four basic types of relationships between two variables.Which of the following is NOT one of those four basic types?

An index number,constrained to fall between -1.0 and +1.0,that communicates both the strength and the direction of a linear relationship between two scale variables is a:

The degree to which the observed frequencies depart from the expected frequencies is expressed in a single number called the:

Chi-square analysis is best interpreted as a prerequisite to looking more closely at the two variables to discern the nature of the association that exists between them.

To reveal the nonmonotonic relationships found to be significant in cross-tabulation tables,researchers often turn to PowerPoint presentations,as pictures will show the relationships well.

A correlational survey was repeated many,many times and computed the average for a correlation that was not significant across all of these surveys,however,eventually the researcher would get some statistical significance.

In using the Pearson product moment correlation,positive correlation coefficients reveal that the relationship is increasing: Larger quantities of one variable are associated with larger quantities of another variable.

When a researcher refers to finding that a systematic relationship exists between the two variables of interest in the population,he or she is referring to which relationship characteristic?

Any correlation that is ? absolute value of .20 is typically uninteresting to marketing researchers because it:

The frequencies table(often referred to as the observed frequencies table)contains calculated numbers determined from the completed tabulation.

A curvilinear relationship means a very smooth curve pattern.However,it does not clearly describe the association.
