Researchers control factors that might influence a dependent variable by means of

B) replication.
C) naturalistic observation.
D) operational definitions.

Question

Quizplus · Accepted Answer

Random assignment allows researchers to control or balance for factors that might influence a dependent variable by randomly assigning participants to different experimental conditions. This helps ensure that any differences observed between groups are due to the manipulation of the independent variable, rather than pre-existing differences in the groups themselves. Replication is a method for establishing the reliability and validity of research findings, but it does not directly control for extraneous variables. Naturalistic observation involves observing behavior in a natural setting, which does not involve direct control of factors that might influence the dependent variable. Operational definitions are necessary for clearly defining and measuring variables, but they do not directly control for extraneous variables.
