#8
What is a placebo in experimental research?
A substance that has no effect on participants
ExplanationPlacebo is a substance having no effect on participants.
#9
What is a confounding variable in experimental research?
A variable that affects both the independent and dependent variables
ExplanationConfounding variable affects both independent and dependent variables.
#10
What is external validity in experimental research?
The extent to which the results can be generalized to other settings
ExplanationExternal validity refers to the extent of generalizability of results.
#11
Which of the following is an example of a quasi-experimental design?

What does it mean if a study has internal validity?
The study accurately measures what it intends to measure
ExplanationInternal validity means the study accurately measures what it intends.
#13
Which of the following is an example of a single-blind experiment?
The participants are unaware of the treatment conditions, but the experimenter is aware
ExplanationSingle-blind experiment involves participants unaware of treatment conditions, but the experimenter is aware.
#14
What is the purpose of using control groups in experimental research?

Random selection refers to selecting participants randomly, while random assignment refers to assigning participants to groups randomly
ExplanationRandom selection is selecting participants randomly, while random assignment is assigning them to groups randomly.
#19
What is random assignment in experimental research?
Assigning participants to groups without any pattern
