#2
What is a dependent variable in an experimental study?

It involves manipulation of variables
It relies solely on observational methods
It studies naturally occurring phenomena
#4
What is the purpose of a control group in an experiment?

To administer treatment
To measure the dependent variable
#5
Which of the following is a disadvantage of experimental research?
It allows for precise control over variables

It is less time-consuming than other research methods
#6
What is a placebo in experimental research?

A variable that remains constant throughout the study
#8
What is external validity in experimental research?
The extent to which the results can be generalized to other settings

To control for confounding variables
#11
What is counterbalancing in experimental research?
Balancing the budget of the research study
Ensuring that each participant experiences the experimental conditions in a different order
Ensuring that the experimental and control groups have an equal number of participants
Balancing the distribution of demographic characteristics across groups
#12
What is the purpose of replication in experimental research?
To manipulate variables to assess their effects
To verify the reliability and generalizability of research findings
To conduct the study in multiple locations
