ANOVA

X2

F ratio

Z test

Scheffe's S

4.

In a research presentation, a supporting material known as "analogy" is defined as:

a critical incident selected to prove an overarching claim; brief rather than detailed stories.

numerical data used in the collection, analysis, and interpretation of data, but also found in data collection planning.

a comparison between two different things to highlight a point of similarity; not offered as conclusive proof for an argument, but may be useful to clarify the argument or presenter's position.

an implicit comparison between two unlike things that actually have something important in common; expresses the unfamiliar in terms of the familiar, achieving its effect via association, comparison, and resemblance.

verifiable data about situations that exist or events that are known to have occurred; often involving statistical data.

6.

Visuals are important in a research presentation because:

Recall accuracy varies as a function of an item's position on a list or an argument's sequence.

The Motivated Sequence produces superior immediate recall though sight visualization.

About 40 percent of us are visual learners, people who learn through seeing.

The narrative pattern of organization results in significantly favorable attitudes toward the presentation through visuals.

7.

Which statistical technique identifies homogeneous subgroups of study objects or participants and then studies the data by those subgroups?

		Multiple regression
		Cluster analysis
		Discriminant analysis
		Factor analysis
		Multidimensional scaling
