Researchers are almost always confronted with different aspects and concepts that accompany reliability and validity. ... Beginning with reliability, the first of the three methods is the test re-test. This assesses test reliability in which the researcher repeatedly applies the same test to the same group of participants on two different occasions. ... The second way to establish reliability is the split-half method. ... The third way as in all methods establishes reliability by showing that two or more measures of the same variable are in agreement. ... These errors are factors that contribute to enhancing the measurement of reliability.
