In quantitative research are replication and falsification the same?

Answer 1

They are not the same. Falsification refers to the susceptibility that a hypothesis or theory has to be proven wrong. In other words, we want to test our theories an hypothesis, to prove it right or wrong. Think about a contrary case: tautological arguments, these arguments can never be proven wrong. Falsification refers to the ability of test a hypothesis or a theory.

Replication on the other hand, is related to be able to reliably find the same results if we do the same experiment repeatedly.
