Exam 8: Complex Designs

The natural groups design is effective for establishing

Complex designs enhance researchers' ability to test hypotheses derived from theories because complex designs

Suppose the overall analysis of variance of a complex design indicates there is no interaction effect.Which of the following analyses should be done as the next step in analyzing this experiment?

A researcher examined whether people's responses to injustice depend on whether the offender in a hypothetical scenario is a male or a female,and whether the offender apologized (or not)after the offense.Participants were randomly assigned to the gender of the offender condition (female,male)and apology condition (present,absent). Participants read a hypothetical scenario in which a person (male or female)acted unjustly and the action results in severe harm.Half of the participants read that the offender apologized; the other half read the same scenario except no apology was mentioned.Participants then rated the extent to which they would forgive the offender using a 0 (no forgiveness)to 9 (complete forgiveness)rating scale.The researcher predicted that participants' forgiveness would be greater following an apology compared to the apology-absent condition.The researcher also predicted that the gender of the offender would have no effect on forgiveness. The researcher observed the following means: Did the results support the researcher's predictions? Explain why or why not.

A student is trying to determine whether an interaction effect is present in an experiment with a 2 * 2 design.The data are summarized in a table.Which of the following methods should the student use to estimate whether or not an interaction effect is present?

An experiment that is described as a 3 * 3 * 2 is one that has

The interpretation of main effects obtained in a complex design is critically dependent on whether

A researcher examined whether people's responses to injustice depend on whether the offender in a hypothetical scenario is a male or a female,and whether the offender apologized (or not)after the offense.Participants were randomly assigned to the gender of the offender condition (female,male)and apology condition (present,absent). Participants read a hypothetical scenario in which a person (male or female)acted unjustly and the action results in severe harm.Half of the participants read that the offender apologized; the other half read the same scenario except no apology was mentioned.Participants then rated the extent to which they would forgive the offender using a 0 (no forgiveness)to 9 (complete forgiveness)rating scale.The researcher predicted that participants' forgiveness would be greater following an apology compared to the apology-absent condition.The researcher also predicted that the gender of the offender would have no effect on forgiveness. The researcher observed the following means: What are the means for the main effect of the Offender Gender variable? [Be sure to specify which mean belongs with each condition.]

The overall effect of each independent variable in a complex design is called

An interaction effect is likely to be uninterpretable when this problem in measurement occurs:

The researcher observed the following means: Describe the research design the researcher used,including the type of variables,and identify the conditions that are created using factorial combination.
