Lesson 7 Flashcards
These are measurable elements that can vary or take different values along some dimensions
Variables
Expresses a potential relationship between two kinds of variables.
Experimental Hypothesis
It is the dimension that the experimenter manipulates. the antecedent that the experimenter chooses to vary
Independent Variable
T/F
IV must be given at least two possible values in every experiment
True
T/F
researchers rely on experimentally controlled variations to study their effects
False - naturally occurring variations
T/F
Preexisting characteristics should be evenly distributed among the subjects
True
T/F
subjects should be exposed to the same treatment
True
It is the particular behavior that we expect to change. also known as the outcome
Dependent variable
T/F
we can explain the behavior from a scientific viewpoint without the antecedent
False
It specifies the precise meaning of a variable within an experiment: It defines a variable in terms of observable operations, procedures and measurements.
Operational Definition
T/F
It is called an operational definition because it clearly describes the operations that are not directly involved in manipulating or measuring the variables in an experiment.
False - directly involved
T/F
The experimental operational definition specifies the exact procedure for creating values of the independent variable.
True
T/F
The measured operational definition specifies the exact procedure for measuring the dependent variable.
True
T/F
Hypothetical constructs are constructs that are directly observable and explain the behavior
False - are unseen processes postulated to explain behavior.
T/F
Many psychological variables are observable constructs, that is, constructs that cannot be observed directly. We infer their existence from behaviors that we can observe.
False - Hypothetical constructs
T/F
Something that cannot be seen must be defined by observable dimensions before we can deal with it scientifically.
True
