Document Summary

One independent variable manipulated (at least 2 levels) One dependent variable measured (response or outcome is because of the indepdnent variable) Experimental variables: manipulated: variable that is controlled, measured: variable that is simply recorded or measured, i(cid:374)depe(cid:374)de(cid:374)t: the (cid:373)a(cid:374)ipulated (cid:448)aria(cid:271)le. Re(cid:373)e(cid:373)(cid:271)er (cid:862)the resear(cid:272)her has independence in assigning people differe(cid:374)t le(cid:448)els(cid:863: conditions: levels of the independent variable e. g. the pasta experiment: the bowl size, small and large, are the conditions, dependent: the measured variable aka the outcome variable. How the participant responds on the measured variable depends on the level of the independent variable: control variables (conditions): any variable an experimenter holds constant on purpose to make sure they are varying one thing at a time. E. g. of violation of experimental control: condition 1 run in the morning and the (cid:862)(cid:272)o(cid:374)trol(cid:863) (cid:272)o(cid:374)ditio(cid:374) ru(cid:374) i(cid:374) the after(cid:374)oo(cid:374), the ti(cid:373)e of da(cid:455) (cid:272)ould desig(cid:374) a confound.
