Chapter 7 Flashcards
It is the antecedent condition or treatment manipulated by the experimenter
Independent Variable
It is the indicator of change in behaviour
Dependent Variable
It defines exactly what was done to create the various treatment conditions of the experiment
Experimental Operational Definitions
It specifies the procedures used to measure the impact of independent Variable
Measured Operational Definitions
The degree to which scores on the measuring instrument correlate with another known standard for measuring the variable being tions in the experiment were actually caused by studied
Concurrent Validity
An error that occurs when the value Interrater reliability The degree of agreement of an extraneous variable changes systematically along with the independent variable in an experi- ment; an alternative explanation for the findings that threatens internal validity
Confounding
The degree to which an operational definition accurately represents the construct it is intended to manipulate or measure.
Construct validity
measure reflects the content of what is being measured.
Content Validity
A variable other than an independent or dependent variable; a variable that is not the focus of an experiment but can produce effects on the dependent variable if not controlled
Extraneous Variable
The degree to which manipulation technique is evident
Face validity
A threat to internal validity in which an outside event or occurrence might have produced effects on the dependent variable
History Threat
Concepts used to explain
unseen processes, such as hunger, intelligence, or learning; postulated to explain observable behavior.
Hypothetical Construct
A threat to internal validity produced by changes in the measuring instrument itself
Instrumentation threat
The degree to which different items measuring the same variable attain consis tent results.
Interitem Reliability
The certainty that the changes in behavior observed across treatment condition in the experiment were actually caused by the independent variable
Internal validity
