In understanding "controlling for" a third variable, which of the following is a similar concept?
A)Creating a longitudinal study
B)Identifying subgroups
C)Creating an operational definition
D)Conducting a replication

Question

Quizplus · Accepted Answer

Identifying subgroups is a similar concept to controlling for a third variable because both methods involve isolating and analyzing the effects of a specific variable while holding other variables constant. In identifying subgroups, researchers isolate groups with similar characteristics to better understand the effects of a specific variable. Similarly, controlling for a third variable involves identifying a variable that may be influencing the relationship between two other variables and holding it constant to better understand the true relationship between those two variables. Longitudinal studies, operational definitions, and replications are not necessarily related to controlling for a third variable.
