Final answer:
Reliability refers to the consistency of producing the same result in data collection. It means that the same outcomes are produced under the same conditions.
Step-by-step explanation:
Reliability refers to the ability to consistently produce a given result. In the context of data collection, reliability means that the same results are produced under the same circumstances. For example, in a psychology study, if a measurement tool consistently produces the same outcomes when administered to the same group of participants, it can be considered reliable.
