Reliability and Validity Reliability and validity are important with any kind of research. Without them research and their results would be useless. This paper will define the types of reliability and validity as well as give examples of each. Both the data collection methods and the data collection instruments used in human services research will also be given. This paper will also look into why it is important to ensure that data collection methods as well as the instruments are reliable and

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

what is the difference between reliability and validity in what respects are they similar The real difference between reliability and validity is mostly a matter of definition.

Reliability and Validity Researchers tend to be peculiar with how they conduct their study and which study method they choose to implement on their subjects. When various tools are examined for measure in behavioral research‚ researchers tend to prefer high validity and reliability (Rosnow & Rosenthal‚ 2008). To understand this concept‚ one must comprehend the meaning and the difference between reliability and validity and how this applies to human services research. Without the full knowledge

Like internal validity‚ there can also be threats to external validity‚ & this can be an explanation of how researchers may be wrong in making a generalisation. For instance‚ researchers may conclude that the results of their study (which was done in a specific place‚ with certain types of people‚ & at a specific time) could be generalised to another context. For instance it could have been at another place‚ with different people‚ at a later time‚ even if these factors are only slightly different
