As the video games industry grows larger in popularity by the day, it becomes a subject of objection more and more and people split into two teams as a result. On the first hand, a group claims that video games are harmful and should be banned because of their connection with aggression, while on the other hand, a group believes that video games have a positive impact on young people. An article titled” Why We Need Violent Video Games” was written by Ethan Gilsdorf in order to persuade readers that

example, you wouldn’t subject the individual to personality testing unnecessarily. Instead, you’d want to make sure that the test being given to the test subject is accurately assessing the intelligence quotient (IQ). Construct-related evidence of validity often involves a process that identifies the real meaning or purpose of the test either through repetition or by compiling multiple sources of evidence. The collection of this evidence not only verifies that the tests actually measures what it is

Results indicated that the VADPRS had high concurrent validity, which demonstrated that the VADPRS was measuring a similar construct from the C-DISC-IV but they were not equivalent (Wolraich et al., 2003). The VADPRS was also compared to the Vanderbilt ADHD Teacher Diagnostic Rating Scale (VATDRS) and the C-DISC-IV

Evaluation of a Performance Assessment: edTPA James (Monty) Burger Texas A&M University Evaluation of a Performance Assessment: edTPA Teacher effectiveness is of the utmost importance to ensure student success. However a valid and reliable performance assessment to evaluate teacher effectiveness has historically remained elusive. Recognizing this need, Stanford University developed the edTPA (formerly Teacher Performance Assessment) to specifically measure teacher

alpha is a statistic that normally used in measure the internal consistency or reliability of a instrument (Mohsen and Dennick, 2011). The instrument cannot be valid unless it is reliable. And the reliability of the instrument does not depend on validity. The most used of cronbach's alpha is to measure the reliability. The cronbach's alpha is expressed as a number between 0 and 1. Before the test employed by

Both reliability and validity are essential to the research process. Reliability and validity ensures that research data is both valuable and useful. Reliability is essentially, the ability to repeat the finding of research (Leedy & Ormrod, 2009). Research proves its reliability by yielding the same results numerous times. Validity is essentially, the believability of the research (Leedy & Ormrod, 2009). Research proves its validity by the providing legitimate and honest research. In research there

Content validity is often seen as a prerequisite to criterion validity, because it is a good indicator of whether the desired trait is measured. If elements of the test are irrelevant to the main construct, then they are measuring something else completely, creating potential bias. In addition, criterion validity derives quantitative correlations from test course. Content validity is qualitative in nature, and asks whether a specific element enhances or detracts from a test or research program

Establishing Reliability and Validity In conducting a research or survey, the quality of the data collected in the research is of utmost importance. One’s assessment may be reliable and not valid and thus this is why it is important that when designing a survey, one should also come up with the methods of testing 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

participants’ beliefs and perceptions of their participation to increase HCPs’ HH adherence. Validity Polit and Beck (2012) define validity as “a quality criterion referring to the degree to which inferences made in a study are accurate and well-founded; in measurement, the degree to which an instrument measures what it is intended to measure” (p. 745). Internal Validity Polit and Beck (2012) define internal validity as “the degree to which it can be inferred that the experimental intervention (independent
