Reliability analysis
Reliability analysis is a statistical method used to assess the consistency, stability, and dependability of a measurement instrument or a system. It helps to determine the extent to which a measurement or a system produces consistent and accurate results over time.
In the context of measurement instruments, such as questionnaires, reliability analysis evaluates the degree to which the instrument consistently measures what it is intended to measure. It assesses the extent to which the items or questions within the instrument yield consistent responses from participants or respondents.
