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.
Reliability is a measure of the internal consistency and stability of a measuring device. Validity gives us an indication of whether the measuring device measures what it claims to. Internal consistency is the degree in which the items or questions on the measure consistently assess the same construct.
