Control Variables And Reliablity Flashcards
(6 cards)
Goal
•identify and control extraneous variables so they done becoming confounding variables
•situational variables -variables connected with research situation (eg temp time of day lighting and materials )
•pp variables-variables connected
Random allocation
•pps should be randomly allocated to groups to reduce pp variables
Counterbalancing
•used to combat problem of demand characteristics
Randomisation
•when all aspects of research are dictated by chance and not by researcher
Standardisation
•process in which all situational variables of a procedure used in research are kept the same
Demand characteristics
•occur when pps try to make sense of teacher may chance behaviour to support or disrupt investigation
