Question: exploratory questions
Answer:
to get an idea, explore, do not give definitive answer, "what if"
Question: descriptive questions
Answer:
characterize, explain, describe, "what is" "how"
Question: relational questions
Answer:
relationship between variables, "does" "is"
Question: experimental research design
Answer:
used to determine the causes of behavior that can explain why it occurs
Question: quasi-experimental design
Answer:
used to identify the relationship between preexisting variables
Question: nonexperimental design
Answer:
used to describe variables and predict the relationship
Question: an experiment includes three key elements that allow cause- and-effect conclusions and
control
Answer:
randomization, manipulation, comparison/control group
Question: experimental research strength
Answer:
cause and effect, strong evidence, 3 controls
Question: experimental research limitation
Answer:
, behavior might not be the same in natural environment hard to assure adherence to protocols lack
framework time and money hawthorne effect
Question: Randomization
Answer:
each individual is given an equal, random chance of selection
Question: cofounding variable
Answer:
unanticipated variable that could be causing a change in measured variables
