Exam 10: Complex Experimental Designs

In order to find a curvilinear relationship,the researcher needs to use

A researcher manipulates a defendant's appearance (attractive,average,or unattractive)and gender (male or female)to study how these variables affect judgments of criminal behaviour.How many interactions are possible in this design?

Which statement is true of a factorial design?

A 4 x 3 factorial design would have how many conditions?

Dr.Parker finds that judgments of responsibility for an automobile accident is greater for male drivers if the outcome is severe than if it is mild.However,for female drivers,ratings are the same irrespective of the outcome.These findings suggest

The main reason to use a 2 x 2 factorial design instead of two separate experiments (with one IV per experiment)is to

If the means from a 2 x 2 study are displayed in a graph and the lines on the graph are perfectly parallel,then what can you conclude?

Participants were asked to read a poem that was written by a male or female author who they were told was a college English major or an English professor.The participants rated the poem written by the professor as being of higher quality than the poem written by the student.From these results,one can conclude there was

A researcher believes that driving performance during daytime versus nighttime will vary depending upon whether the road is dry or wet.In this study,road condition would be a(n)

You have designed an experiment manipulating weight of an individual (normal,over);age (young,middle,old);and gender (male,female).How many interactions are possible?

In a 2 x 2 x 2 design,how many possible results can be evaluated?

A researcher examines the physical attractiveness of a driver involved in an automobile accident (unattractive,average,or attractive)and the severity of damage caused ($500,$1500,or $2500)on judgments of responsibility assigned to the driver.Which of the following represents the design?

A researcher studies the effect of interpersonal distance (near,far)and personality type (introvert,extrovert)on feelings of anxiety.The researcher has used a(n)________ design.

A researcher designs a study where participants are randomly assigned to one of two conditions.Each participant is then measured under two different circumstances.This is an example of a(n)_____ design.

A researcher finds that for female applicants,the likelihood of being hired for a job increases as their work experience increases.However,for male applicants,the likelihood of being hired decreases as their work experience increases.This finding would suggest

A 2 x 2 factorial design was used to study the effects of participant gender and style of persuasion on attitude change using 40 individuals.This is an example of a(n)________ design.

An educational researcher examines the effect of speaker credibility on attitude change in university and community college students.The PV in this design is

You have designed an experiment manipulating room temperature (cold,warm,or hot);noise level (quiet or loud);and room colour (pink,blue,or black).How many main effects are possible?

You design an experiment that manipulates the following variables: method of presenting material (visual,auditory);difficulty of material (easy,difficult);and amount of material (low,moderate,high).For a completely independent groups design with 10 participants per group,how many participants will you need?

In a 4 x 3 factorial design,for a completely repeated measures design,how many participants will you need to have 20 participants per condition?
