Research Flashcards
The independent variable is…
The variable that is manipulated by the researcher to witness it’s effect on the D.V.
(The treatment/intervention used)
What is the dependent variable?
The measure of behaviour
What does internal validity refer to?
An experiment has high internal validity it convincingly demonstrates the I.V. caused the effect on the D.V.
When does an experiment have high external validity?
When it’s findings can be generalised to other people, places, behaviours or treatments
The 3 purposes of science are:

Research that determines the relationship between variables
Correlations help us describe the ____ and ____ of the relationship between two variables
Strength; direction
Experimental:
The controlled manipulation of variables to show cause and effect
The most commonly used experimental designs are:
Group designs
An experimental design that compares large ____ of Ps to determine the effects of I.V.s on D.V.s is known as
Group designs
What is the procedure in conducting a group design?
Randomly Assign Ps to groups: some experimental, some control.
What experimental design uses fewer Ps (not divided into groups) to determine IV on DV?
Single subject designs
