QUESTION_1: Measurement instruments often provide the basis upon which an entire research effort rests. As Leedy and Ormrod (2005) suggest, “Just as a building with a questionable foundation is unlikely to be safe for habitation, so, too, will a research effort employing faulty measurement tools provide little of value in solving the problem of investigation” (p. 91). Demonstrate the ability to determine the validity and reliability of measurement instruments by answering the following: Explain the difference between an instrument’s validity and its reliability; outline at least four forms of validity and provide specific examples of each; discuss ways in which a researcher could enhance the validity of a self-constructed research instrument, describe at least four types of reliability and provide specific examples of each; and suggest at least three ways a researcher could enhance the reliability of a measurement instrument.
