| | | All of the above are true 2. 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 3. 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 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 | | | | Varimax approach 5. 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 | | | | | | |
