Establishing Reliability and ValidityIn conducting a research or survey, the quality of the data collected in the research is of utmost importance. A person's assessment may be reliable and invalid. This is why it is important that when designing a survey, methods are also proposed to test the reliability and validity of the assessment tools. For MADD (Mothers Against Drunk Driving) to conduct a survey, the questions they propose to use must pass the validity and reliability test to be able to conclude that the survey is reliable and valid. This investigation will attempt to uncover risk factors that contribute to drunk driving among adolescents or young adults. Reliability can be defined as the statistical measure of how consistent and repeatable a research tool or instrument can measure what it is intended to do (Litwin, 1995, p.6). Validity, on the other hand, is the measure of how well the tool or instrument can actually or correctly measure what it is designed to do (Miller and Kirk, 1986, p. 19). Reliability and validity are asymmetric, meaning that one can achieve ideal reliability without validity, but perfect validity results in perfect reliability. But theoretically, perfect validity cannot be achieved because no instrument or tool can be perfectly standardized and no assessment or experiment can be perfectly controlled (Miller and Kirk, 1995, p. 21). Normally, reliability tests are carried out but none are carried out on validity. To evaluate the reliability and validity of the questions that MADD wishes to use in its survey, several tests will be run on the questions to evaluate the different types of reliability and validity. To establish the validity and reliability of this survey, a pilot survey......middle of document......and the validity of the questions MADD wishes to use, we can then be confident that the data from the The survey collected will be close to the true value and that it measures the risk factors that play an important role in drunk driving among adolescents. It is not possible to carry out a perfect survey, but with good standardization of research tools we can achieve a high level of reliability and therefore a very valid survey result.
