1Dr. Shingwauk designed an experiment in which participants listened to a persuasive speech delivered either by a very tall person or a person of average height. In addition, the speeches were delivered by people wearing either business clothes or casual clothes. Dr. Shingwauk asked listeners to fill out a survey about impressions of the speaker"s credibility. In this study, what is Dr. Shingwauk looking to determine?
- ADoes a double-blind procedure lead to greater credibility of speakers, independent of the effects of appearance?
- BDo height and clothing style interact to influence judgements of credibility?
- CDoes persuasion interact with any other factors?
- DDoes the persuasiveness of the speech depend on the additive effects of height and clothing style?
2Which of the following must be true of a scientific theory?
- AIt is well established and not disputed.
- BIt is accepted by others.
- CIt is testable.
- DIt is correct.
3What is an independent variable in an experiment?
- Aa variable that provides an alternative explanation for the results of the experiment
- Ba variable that is held constant across experimental conditions
- Ca variable that the experimenter believes will change in value because of systematic correlations that exist in the experiment
- Da variable deliberately manipulated by the experimenter
4Dr. Malm predicts that if teachers ignore students who act up in class, fewer students will act up in class. What is the scientific term for Dr. Malm"s prediction?
- Aoperational definition
- Binferential statistics
- Chypothesis
- Dtheory
5If we view an experiment as an attempt to establish a cause-effect relationship, how can we define the relationship between the variables in an experiment?
- AThe independent variable is the cause, and the control variable is the effect.
- BThe dependent variable is the cause, and the independent variable is the effect.
- CThe control variable is the cause, and the independent variable is the effect.
- DThe independent variable is the cause, and the dependent variable is the effect.
6Which of the following terms refers to differing approaches to the observation, measurement, manipulation, and control of variables in empirical studies?
- Avalidity operationalizations
- Bresearch methods
- Cstatistical analyses
- Dinductive techniques
7What is the purpose of the control group?
- Ato isolate the effect of the independent variable on the dependent variable
- Bto correlate the dependent variable with the independent variables
- Cto make statistical significance more likely
- Dto make the experiment more complex
8Jackson is working with a company to help them develop more effective training programs for their employees. He has spent a great deal of time reviewing all the documentation the company has about previous training opportunities they have provided for their employees.

- Bdirect observation
- Cpsychological testing
- Darchival research
9What is an extraneous variable?
- Athe same thing as a dependent variable
- Ba variable, other than the independent variable, that may influence the dependent variable
- Ca variable that is completely irrelevant to both the independent and dependent variables
- Da variable that affects the control group but not the experimental group
10Dr. Hessels is examining how different people respond to frightening events. She will have participants walk through a haunted house at a local amusement park, and each participant will be outfitted with a heart monitor. She will use the changes in heart rate as a measure of stress. What are two ways that such changes in heart rate can be described?

11Dr. Kalmagura plans on introducing a new exam review procedure in his chemistry classes. To check the effectiveness of the new procedure he is going to have half his students try the new technique for one semester, while the remaining students review in the way they have always done in the past. He asks each student to decide whether they would like to use the new technique or the standard technique. What procedure is illustrated in this example?
- Aa double-blind research design
- Binformed consent in research
- Cthe use of non-random assignment
- Da correlational research design
12What do we call two variables that are linked, and their individual effects cannot be separated out?
- Acodependent
- Bconfounded
- Cindependent
- Ddependent
13Researchers who were studying plant growth raised plants in two separate rooms. One room had taped conversations playing 24 hours a day; the other room was silent. The researchers found that the plants grew better in the room that had the conversations playing. In this study, what would you call the type of room (silent versus conversation)?
- Aplacebo
- Bindependent variable
- Cdependent variable
- Dextraneous variable
14What is an operational definition?
- AIt provides a logical basis for each term.
- BIt states relationships to other variables.
- CIt describes the actions and procedures used to measure or control a variable.
- DIt separately defines each term used.
15In an experiment designed to test memory processes, one group was given special instructions and asked to group the items on a list into categories while trying to memorize them. A second group of participants was given the same list, but did not receive any special instructions. In this study, which group is the experimental group?
- Athe group that received the special instructions
- Bthe group in which the participants remember the most items from the list
- Cthe group that did not receive any special instructions
- Dthe group in which the participants remember the fewest items from the list
