Which variables are those that a researcher chooses to study in order to assess their possible effects on one or more other variables?
ADependent
BIndependent ✓ Correct
CExtraneous
DConfounding
Correct answer: (B) Independent — The variables chosen to study for their effects on others are the independent variables, so that is the answer.
Explanation
★The variables chosen to study for their effects on others are the independent variables, so that is the answer.
★The independent variable is the presumed cause that the researcher chooses to study.
★So it is selected to assess its possible effects on one or more other variables.
★The dependent variable is the effect that is measured, not the chosen cause.
★An extraneous variable is an unwanted outside factor, not deliberately studied for its effect.
★A confounding variable distorts results, so the variables chosen for their effects are the independent variables.
