Experimental methodCorrect Answers ✅✅A researcher causes
the independent variable to vary and records the effect of the IV on the
dependent variable. The DV must be operationalised.
ControlCorrect Answers ✅✅(Refers to) The extent to which any
variable is held constant or regulated by a researcher
Extraneous VariablesCorrect Answers ✅✅'Nuisance' variables
that do not vary systematically with the IV. A researcher may control
some of these.
Confounding VariableCorrect Answers ✅✅Change systematically

due to the CV or the IV. CVs must be controlled.

Double Blind DesignCorrect Answers ✅✅Both ps and researcher
don't know the aims of the study to reduce demand characteristics and
investigator effects.

Differences among participants, overcome by a large sample size which
dilutes any extremes
