Replicability and Falsifiability (features of science) Flashcards
What is replicability?
the ability to carry out the method of a study at another time
What does replicability involve?
repeating the procedure of a study at another time and obtaining
similar results.
why is being able to replicate a study an important feature of science?
-it provides a way to check and verify scientific information.
-A high level of consistency in the findings means that researchers and those reading the research, can be confident that the findings are really what the researcher said they were.
what must researchers do to achieve replicability?
-Researchers need to record their methodology carefully so that the same standardised procedures can be repeated easily.
-This would also require accurately operationalising variables and measurement systems.
How are reliability and replicability different?
Having a replicable (repeatable) method enables findings to be checked for reliability (consistency).
What may unreliable findings imply?
flaws or a lack of contort within the method and would therefore be of limited use in theory construction
what does falsifiability refer to?
being able to prove a theory wrong
what is a null hypothesis?
a testable statement that refutes the theory being tested
Why is it necessary to include a null hypothesis in any scientific study?
-As part of deductive reasoning, this would then lead to the theory either being modified or rejected.
-The improved theory would then be retested using the same methodology.
