Question 2

Define the terms replicated research and meta-analysis.Identify the role of replicated research and meta-analysis in hypothesis testing and theory building.

Accepted Answer

The response should include the following:
Replicated research:attempting to repeat findings,sometimes using other procedures,other settings,or different groups of participants.
Meta-analysis:a statistical procedure allowing psychologists to combine the results of many separate studies into one overall conclusion.
Replication and meta-analysis reflect the scientific ideal that hypotheses are subject to stringent test and ultimately supported only if they are confirmed many times across a range of specific situations.Our confidence in a hypothesis is increased if it is supported by replications and meta-analyses; these procedures affirm the generality of a hypothesis.Such confidence in a hypothesis in turn contributes to the development of more accurate theories,or explanations,of thought and behavior.
