It is the extent to which results of a test truly measure what they are supposed to measure. Validity is the extent to which a test that is designed to measure a specific concept accurately measures that concept. 05 is evidence of test-retest reliability. 7 with a statistical significance of p <. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for test-retest reliability using a correlation statistic. This can be measured by administering the same test twice over a period of time to the same group of individuals. This is important for getting results to replicate with a single test under similar conditions. Test-retest reliability provides information on how consistent the same test is over time. 7, this indicates high individual test reliability.

Individual test reliability is measured using a statistic called Cronbach’s Alpha. That is, it is a measure of how closely related a set of items are as a group within a test.

Individual test reliability (also known as internal consistency) provides information on the consistency of items within a single test. Two important types of reliability are individual test reliability and test-retest reliability. Under the same conditions, the higher the reliability of a test. The more consistent results are when achieved Reliability is the extent to which results can be reproduced when research is repeated under the same conditions. Reliability provides information on the consistency of a measure, and validity provides information about the accuracy of a measure. They indicate how well a method, technique, or test measures what it intends to measure. Reliability and validity are two ways researchers can evaluate the quality of assessment tools. On both these criteria, the Real Colors® instrument performs well. And when assessing validity, one must ask, “Does the instrument measure what it intends to measure?”. When assessing reliability, one must ask, “Does the instrument give consistent results?”. Because of our commitment to ongoing research and development, Real Colors® finds it necessary to periodically assess the reliability and validity of its own assessment. Since 1993, Real Colors® has sought to be a provider of simple, easy to apply, research-based tools and training that will allow people to better understand themselves and others. It is from the innate desire to understand human behavior and the motivations behind it that the Real Colors® instrument was developed.

Since the time of Hippocrates, researchers have continued to build on the body of research furthering the desire to better understand themselves and each other. The Greek philosopher, scientist, and physician Hippocrates wrote over twenty-three hundred years ago that all human beings could beĭivided into four distinct personality types. For centuries, people have searched for a convenient way to peek into the human mind.
