Reliability and Validity

When examining the data they have collected, it is essential for researchers to determine to what degree is their data consistent.  There are many methods by which researchers can assess the reliability of their instruments.  Through different statistical procedures, researchers will evaluate the reliability coefficient to ascertain to what extent their data is consistent.  The reliability coefficient is generally a numerical value between 0.00 and 1.00, where the coefficients of reliability are numerical values close to 1.00. 

The test-retest approach to reliability is used to assess how consistent a measured group of subjects tested with the same measuring instrument remain over time.  Using this method, a researcher administers the same test twice to the same group of people, using the s
