(a) Incorrect. (b) Correct. For (a), a factor in an experiment represents a variable that is controlled by the researcher while modifying its conditions. This indicates that the experimenter determines the variable's levels throughout the study, which can be two or more levels that form treatments. Controlling a factor by establishing different levels is crucial to observe resultant trends. For (b), randomization refers to the selection process for participants in an experiment to prevent bias. By implementing randomization, the groups involved will be similar, thereby eliminating the risk of selection biases arising from underrepresented demographics.
