Which of the following is true concerning independent and dependent variables in classical experiments?
A) a variable can be an independent in one experiment and a dependent in another
B) once a variable is designated as an independent variable in one experiment, it can never be used as a dependent variable in another
C) a classical experiment examines the effect of a dependent variable on an independent variable
D) an independent variable in a classical experiment is viewed as the effect because it is dependent upon another variable

Question

Quizplus · Accepted Answer

The designation of a variable as independent or dependent depends on the specific experimental design and research question being investigated. Therefore, a variable can be an independent variable in one experiment and a dependent variable in another. Option B is incorrect because variables can switch roles based on the research question being investigated. Option C is not entirely accurate as the classical experiment examines the effect of the independent variable on the dependent variable. Finally, option D is incorrect because an independent variable is the variable that is manipulated or controlled in an experiment, while the dependent variable is the outcome that is observed and measured.
