Reliability - ANSWER Reliability is used to refer to something
that is dependable and will be around about the same' or give
the same outcome every time.

• the measurement instrument, e.g. data collection tool
• the measurement procedure, e.g. research method, type of

groups
• the setting, e.g. laboratory or field
• the location
