Reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.
A reliable instrument produces consistent results regardless of the setting, yet reliability does not ensure accuracy or validity. Validity refers to an instrumentâs capacity to accurately measure what the researcher intended to measure. Reliability must be accompanied with validity regarding an instrument worthy of use in conducting doctoral research. A few simple examples help explain the meaning of reliability and validity.
