Exam 10: Experimental Research

Describe matching, randomization, and blocking as methods to achieve equivalence between experimental and control groups. Discuss the advantages and disadvantages of each.

Which threat to internal validity is controlled by the multiple time series design but not by the other time series designs

A double-blind experiment is one in which:

In experimental research, random assignment:

One of the advantages of experiments over other research designs is that experiments:

Discuss the issues associated with minority participation in social science experiments.

Which of the following is NOT one of the threats to the external validity of experiments discussed in the text

As it relates to experimental research, "gender insensitivity" refers to:

All of the following are disadvantages of experiments EXCEPT:

In experimental research, the independent variables:

In an experiment, teachers' judgments are used to measure the amount of misbehavior among students. The teachers are more likely to judge a given behavior as misbehavior at the posttest than they are at the pretest. This example most clearly illustrates which threat to the internal validity of the experiment

Which of the following is NOT classified as a true experimental design

The example of the horse Clever Hans is used by the text to illustrate which phenomenon

The text describes a field experiment conducted to assess the impact over years of "stand your ground" laws on justifiable homicide rates. This study used which kind of experimental design

Which of the following experimental designs not only controls all of the threats to internal validity but also allows the effects of history and maturation to be measured

Which of the following is NOT a potential threat to the internal validity of experiments

The multiple experimental groups with one control group design is used to:

A researcher attempts to evaluate the impact of a safety-training program that is intended to increase the use of helmets by child bicyclists. About the same time that the training program takes place, the local news media runs a front-page story about a five-year old whose life was saved by wearing a helmet. This case most clearly illustrates the internal validity threat of:

Define and discuss the importance of control groups and control variables in experimental research.

Which of the following might an experimental design lack, resulting in its classification as a pre-experimental design
