Three characteristics of good research question
Three characteristics of good research question
Testable, achievable, specific
Independent variable (IV)
Independent variable (IV)
Factor that is manipulated in an experiment
Dependent variable (DV)
Dependent variable (DV)
Factor measured that changes when IV is manipulated
Hypothesis
Hypothesis
Testable statement of expected DV change as IV changes
Control group
Control group
Group not exposed to the independent variable
Replication
Replication
Running your test/experiment multiple times
Systematic error
Systematic error
Consistent error from faulty equipment; affects accuracy
Random error
Random error
Unpredictable variation in measurement; affects precision
