What is an IV X PV design?
IV X PV design. A factorial design that includes both an experimental independent variable (IV) and a nonexperimental participant (PV). Main effect. The direct effect of an independent variable on a dependent variable.
Which of the following best describes a mixed factorial design?
Which of the following best describes a mixed factorial design? It always assigns different groups of participants to each of the conditions. It typically assigns the same individuals to participate in all the conditions. It either uses a between-subjects design or a within-subjects design.
When a researcher attempts to manipulate more than one independent variable what type of design is he or she using?
Factorial Designs. Two-group designs are inadequate if your research requires manipulation of two or more independent variables (treatments). In such cases, you would need four or higher-group designs. Such designs, quite popular in experimental research, are commonly called factorial designs.
What is a staged manipulation?
Staged manipulation. When events are staged in an experiment in order to manipulate the independent variable successfully. Confederate. Someone who appears to be another participant but is really an accomplice of the researcher.
Which of the following is the main reason a researcher would conduct a staged manipulation?
First, the researcher may be trying to create some psychological state in the participants, such as frustration, anger, or a temporary lowering of self-esteem. Second, a staged manipulation may be necessary to simulate some situation that occurs in the real world.
Which of the following is a disadvantage of using the strongest manipulation possible in a research?
What is a disadvantage of using the strongest manipulation possible in a research? It creates a situation different from a real-world situation. Why do experiments conducted in field settings use unobtrusive measures?
When planning an experimental manipulation one should consider?
when planning an experimental manipulation, one should consider…. the need to maximize difference between the groups.
Which is a critical difference between quasi experimental and experimental designs?
Differences between true experiments and quasi-experiments: In a true experiment, participants are randomly assigned to either the treatment or the control group, whereas they are not assigned randomly in a quasi-experiment.
What is a quasi-experiment example?
This is the most common type of quasi-experimental design. Example: Nonequivalent groups design You hypothesize that a new after-school program will lead to higher grades. You choose two similar groups of children who attend different schools, one of which implements the new program while the other does not.
What type of research is quasi-experimental?
The prefix quasi means “resembling.” Thus quasi-experimental research is research that resembles experimental research but is not true experimental research. Although the independent variable is manipulated, participants are not randomly assigned to conditions or orders of conditions (Cook & Campbell, 1979).
What is the major limitation of the quasi-experimental design quizlet?
quasi-experiments lack random selection of participants. quasi-experiments cannot test for causal relationships. quasi-experiments lack random assignment to conditions. Which of the following represents a one group, pretest-posttest design?
Why do researchers choose to use quasi-experimental designs quizlet?
Sometimes, researchers may rely on quasi-experimental designs because they can not have full experimental control. – 1) This may occur when researchers are unable to manipulate the independent variable and/or researchers are unable to randomly assign participants to different levels or groups.
What important feature of experimentation does Quasi-Experimental Research lack quizlet?
Quasi-experiments provide an important alternative when true experiments are not possible. They also lack the degree of control in true experiments, specifically they lack random assignment.
Which of the following is an advantage of using quasi-experimental designs quizlet?
Which of the following is an advantage of using quasi-experimental designs? They allow researchers to capitalize on random assignment. They allow researchers to enhance external validity.
Which of the following is the most common quasi-experimental design?
nonequivalent groups design
