Basic Between-Subject Design Flashcards
A design in which different subjects take part in each condition of the experiment. They are randomly assigned to the conditions.
Between-subjects design
General structure of the experimenter. The researcher’s plans for testing the hypothesis and not the experiment’s specific content
Experimental design
A statistical estimate of the size or magnitude of the treatment effects. The larger the ________, the fewer subjects needed to detect a treatment effect.
Effect size
The technique of assigning subjects to treatments so that each subject has an equal chance of being assigned to each treatment condition.
Random assignment
An experimental design in which subjects are placed in two treatment conditions through random assignment
Two-Independent groups design
When only two treatment conditions are needed, the experimenter may choose to form two separate groups of subjects
Two group design
Every subject has an equal chance of being placed in any of the treatment conditions
Random assignment
Used to apply a particular value of our independent variable to the subjects and measure the dependent variable
Experimental condition
Subjects in an experimental condition
Experimental groups
Used to determine the value of the dependent variable without an experimental manipulation of the dependent variable.
Control condition
Subjects in a control condition
Control group
An experimental design that can be used to look at behavioral differences that occur when subjects are exposed to different values or levels of the independent variable
Two experimental groups design
An experimental design where there are two also two groups of subjects but the researcher assigns them to groups by matching or equating them on a characteristic that will probably affect the dependent variable
Two matched groups design
Members of the matched pair must have identical scores
Precision matching
The members of a pair must fall within a previously specified range of scores
Range matching
