Aims
What the researchers intend to find out and do during the study
Ethical issues
Conflicting sets of values, moral right and wrongs
Hypothesis
A precise and testable statement
Informed consent
Participants given comprehensive information concerning the nature of the study and their rights
Operationalise
Putting the variables into a testable and measurable form
Standardised procedures
A set of procedures that are the same for all participants, so that the study can be repeated
Extraneous variable
A variable that is not the IV but can affect the results of the experiment (.e.g: time of day)
Confounding variable
A variable that affects the DV in a systematic way, it is unintentionally measured (.e.g: gender or age)
Internal validity
The degree to which the results were caused by experimental manipulation rather than extraneous or confounding variables.
External validity
The degree to which a finding can be generalised
Ecological validity
How it can be generalised to other settings or locations
Population validity
How it can be generalised to other groups of people
Temporal/historical validity
The degree to which it can be generalised to the historical period
Generalise
To be able to understand and relate the findings to everyday life
Mundane realism
How the study mirrors the real world (High mundane realism - very much reflects the real world)
Directional hypothesis
States the expected direction of the study (usually based on previous evidence or theory)
