Exam 9: Choosing the Right Research Design

In a 2 x 2 factorial study,what is the maximum number of main effects that you could possibly observe?

The major limitation of one-way experimental designs is that they only allow researchers to look at o_____ at a time.

If you overheard a researcher say that "each of the three possible main effects in my study was highly significant," you could conclude that the analysis the researcher had conducted was:

Cathryn conducted an experiment that involved administering an anti-anxiety drug to people with a history of Generalized Anxiety Disorder.Participants received 0 mg,50 mg,or 100 mg of the drug.Which participants received a placebo?

A design that incorporates both within-subjects and between-subjects measures of independent variables is known as a:

Simple effects tests are conducted to:

If you plotted the results of a factorial study using lines whose slopes represents mean differences across different experimental conditions,the presence of a statistical interaction would show up in the form of:

To analyze the data from a 2 x 2 factorial experiment,you should conduct:

Is it possible for a statistical analysis to yield three main effects in a 2 x 2 factorial study?

Chloe conducted a 2 x 2 factorial study in which her independent variables were gender and frustration.Her dependent variable was verbal aggression.She found that frustration significantly increased verbal aggression in both women and men (to an equal degree).She also found that,on average,women engaged in significantly more verbal aggression than men did (regardless of frustration level).Chloe seems to have observed:

A counterbalancing technique that guarantees that the average serial position of any given condition in a study is exactly the same for all the unique conditions is known as:

To find out whether participants figured out what was being manipulated in an experiment,an experimenter is most likely to use_________ immediately after participants have completed the study.

In her research on stereotyping,Efrat conducted a very large 2 x 2 (Target Gender x Judgmental Time Pressure)factorial study.She observed an interesting main effect of target gender.However,she did not observe a main effect of time pressure,and she did not observe any evidence for a significant interaction.Efrat's failure to observe a significant interaction could be thought of as evidence for:

Relative to within-subjects designs,mixed-model designs make it easier:

According to the text,carry-over effects are best controlled by:

In comparison with purely between-subjects experimental designs,one drawback of purely within-subjects experimental designs is that:

The simplest possible kind of true experiment is:

When an effect exists at one level of a second independent variable but is weaker or nonexistent at a different level of the second independent variable,the observed pattern is referred to as a:

A Latin square is one specific example of:

A disordinal interaction is the same as:
