Question

Why is the process of replication in research important?

1) It makes samples more representative of the populations they come from.
2) Without it, incorrect results would often go uncorrected.
3) Demand characteristics would have larger effects on data that were not replicated.
4) The Hawthorne effect would increase if research were conducted only once.

Answer 1

Replication in research is important because it enhances the representativeness of samples, helps correct errors, reduces the effects of demand characteristics, and minimizes the Hawthorne effect.

Step-by-step explanation:

Replication in research is important for several reasons:

1. It makes samples more representative of the populations they come from, ensuring that the findings of a study can be generalized.
2. Without replication, incorrect results may go uncorrected, leading to the spread of misinformation.
3. Replication helps reduce the effects of demand characteristics, which are the cues that participants may unintentionally pick up from the researcher and alter their behavior.
4. Furthermore, the Hawthorne effect, which refers to changes in behavior due to the awareness of being observed, would increase if research were conducted only once.
