Replication of a research study is most likely to be facilitated by "operational definitions".
An operational definition is the verbalization of operationalization utilized in characterizing the terms of a procedure expected to decide the idea of a thing or phenomenon. For instance a person who is researching estimating bliss and dejection in understudies chooses to utilize a ten-question satisfaction scale to quantify inspirational standpoint in her subjects. At the end of the day, her operational definition of bliss for this situation is a given subject's score on the test.
