1. 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
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.
2. 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
3. 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.
4. Which approach to cluster analysis involves evaluating the distance between two clusters by first finding the geometric center of each cluster and then computing distances between the two centers?
Euclidean distance
Average linkage method
Maximum likelihood method
Principal components analysis
5. Hypothesis testing of the effectiveness of two experimental manipulations against a control group finds that there is a significant difference in the mean score by group and the null hypothesis is rejected. Which test below can be used to determine where a difference exists?
ANOVA
X2
F ratio
Z test
Scheffe's S
6. Jack is developing the outline for his research report. He is outlining using just a few words to jog his memory when he writes the report. What type of outline is Jack using?
Topic outline
Bullet outline
Sentence outline
Paragraph outline
List outline
7. When conducting an ANOVA, if the F ratio is close to 1, which of the following interpretations is true?

All of the above are true

Antecedent
Component
Extraneous
Intervening
Suppresser
9. The technique used to provide a more simple and interpretable picture of the relationships between factors and variables is called _____.
rotation
regression
resistance
principal components
residual analysis
10. Which of the following measures is used to assess the strength of relationships in cross-classification tables?
Nonparametric measures of association
Parametric measures of association
ANOVA
Regression
R-test
11. Statistics used to assess the strength of relationships for categorical data may be sensitive to all of the following except _____.
table shape
number of cells in the table
type of sample
sample size
marginals
12. Several psychological principles have important implications for speakers. Which of the following is true?
An audience member comes to the presentation with past knowledge of the speaker's topic and will judge the presentation based on selective perception.
An audience member comes to the presentation with limited knowledge of the topic and will remain open-minded throughout the presentation.
Each audience member organizes his or her unique construct of the content presented, which is unrelated to listener experience and openness to change.
There is no need for the speaker to attempt to construct imaginatively how the audience will interpret the message because it is impossible to know in advance.
All of the above
