Example Question #11 : Ib Psychology Sl
What is the main difference between laboratory experiments and field experiments?
Laboratory experiments are conducted in the real world and field experiments are conducted in the lab
Field experiments are more easily controlled
Laboratory and field experiments differ based on the number of subjects
Laboratory experiments are conducted in the lab and field experiments are conducted in the real world
Laboratory experiments are more realistic
Laboratory experiments are conducted in the lab and field experiments are conducted in the real world
The difference between laboratory experiments and field experiments is not the number of subjects, but the place where they are conducted—the lab or the outside world. Lab experiments are more easily controlled, whereas field experiments are more realistic.
Example Question #12 : Ib Psychology Sl
A researcher is curious about how temperature relates to aggression and predicts that as the temperature in a room increases, a measure of the subject's aggression will increase as well. What is the experimental design term for "temperature" in this scenario?
Independent variable
None of these
Hypothesis
Dependent variable
Theory
Independent variable
A variable is described something that varies between people or objects—in this case, temperature and aggression are the variables. The “independent variable” (IV) is the variable that is manipulated by the researcher (temperature) and the “dependent variable” (DV) is the variable that changes as a result of a change in the IV (aggression). A “hypothesis” describes the relationship between variables and is generally what the researcher predicts will happen (i.e. “as the temperature in a room increases, a measure of the subject's aggression will increase as well”). Last, a “theory” is a principle or set of principles that explains a phenomenon.
