Replicability - correct answer Being able to repeat a study and obtain the same
results.
Why replicability is important - correct answer 1. Scientific evidence needs to be
consistent. If the investigation produces the same results when replicated, it is likely to be valid and
reliable. 2. If a study is not repeatable the results cannot be verified to be true (validity). 3. The results
may imply flaws or lack of control within the method and are therefore of limited use in theory
construction.
Objectivity - correct answer This means being unbiased in conducting a study, so that
the data collected are independent of the researchers' individual perspective or is not subjective.
How objectivity can be achieved - correct answer Psychologists use: standardized
instructions, operationalized variables, physical measures of performance. These ensure the researcher
is not affecting the outcome.
If data is not objective it is...? - correct answer Subjective. This means the viewpoint
is likely to be biased and is not independent of the situation.
Empirical methods - correct answer Information that has been gathered through
methods based on direct experience, such as experiments and observation. The opposite is based on
intuition and is not provable.
Falsifiability - correct answer A theory is scientific if it makes clear predictions that
can be objectively tested and could be shown to be wrong by the evidence. The longer a person goes in
trying to prove themselves wrong, without doing so, helps to prove that they are right.
Operationalization - correct answer A science should provide hypotheses, aims and
variables that are clearly defined, to ensure a theory is replicable.
