External, Internal, and Construct Validity

Compare and Contrast the characteristics of external, internal, and construct validity Internal, external, and construct validity are all forms of validity which determines the validity of the research. While they all assess the making of the particular program they differ in the way they are used as discussed below. Construct Validity In the case of construct validity, its characteristic is that it is used to measure characteristics. Commonly used in social science and psychometrics research, the construct validity measures characteristics using a number of sets of observable indicators where the correlation of the given variables is being examined or evaluated. Trochim defines it as “degree to which inferences can legitimately be made from the operationalizations. For Trochim, (Trochim chap. 3,…

Reliability and Validity

Reliability is defined as the consistency of the measurement. The term can also be defined as the extent to which one instrument can be used in a similar way, every time it is utilized under similar circumstance, and with similar subjects. This is what it means to say that the measurements or the instruments are reliable. It is also the repeatability of measurement. Any measurement is considered reliable where the results of the same test are the same. It is crucial to note that reliability cannot be measured, but it is given as an estimate. To find out the reliability of a measurement, it is important to carry out an experiment more than once or use the same instrument for…

Validity and Reliability

The Monte Carlo simulation is used as a method that is used in projects to estimate the risk and uncertainty attached. In construction projects, engineers need to measure the time and the cost involved. These measurements are based on prior experience of the project manager. The time and the value of the project are estimated on the basis of certain assumptions. Monte Carlo simulation works in a way that a random number is selected for the each task. The model is then made which is based on the random numbers. The result that is generated from the model is stored and the process is repeated several times. A normal simulation done through the Monte Carlo method calculates thousands of values….

According to Boghossian

Boghossian characterizes such relativism in terms of the doctrine of Equal Validity. There are many radically different, yet equally valid ways of knowing the world, with science being just one of them. (2) We ordinarily privilege and defer to the variety of techniques and methods — observation, logic, inference to the best explanation and so forth, but not tea-leaf reading or crystal ball gazing — that we take to be the only legitimate ways of forming rational beliefs on the subject (4). The sophistication and complexity behind Boghossian’s discussion threatens to make it less accessible to the non-specialist than one may hope. Based on personal theories and repetitious studying , Boghossian is inviting his reader to accept that there is…

Contemporary use of personality measurement

Describe and evaluate contemporary use of personality measurement and testing, focusing on issues of reliability and validity, using empirical evidence to support your arguments. Personality tests are widely used these days in both professional and informal settings. One may take a personality test online, for example; in order to determine how much like a film character they are, or they may take one in an employment process or clinical setting. This essay, however, will only be looking at formal tests. The tests have many uses, including recognizing psychological disorders or calculating future behaviour (Plotnik, 2002). It is important to note that personality tests are like any other instrument used to increase understanding of a topic and, like all instruments and…

Evaluating Truth and Validity

Truth and validity are two different concepts which should not be confused, although they are usually taken as synonyms in common language. In logic, it is said that the argument is valid when the conclusion follows deductively from the premises. While of the premises and the conclusion is that they are true or false, the arguments are said to be valid or invalid. The validity or invalidity of the argument does not depend on its conclusion to be true. According to Moss (2007) “Understanding Truth aims to illuminate the notion of truth, and the role it plays in our ordinary thought, as well as in our logical, philosophical, and scientific theories. The argument is valid, when you have consistency and…
