Content validity

Validity looks to see if a test measures what it is supposed to measure and if the test does not then it is not valid and should not be used. There are numerous types of test validity discussed in this chapter, but the one that stuck out to me the most was face validity. Face validity just looks to see if the test looks like what it is supposed, but it is important to remember that just because it looks valid does not mean it is. I believe this stood out to me the most because of all the online quizzes that are very popular right now; they are most likely not valid, but they look valid. I can see how easy it would be for someone who does not know a lot about testing, believe those tests are valid and really take to heart what the tests are saying. That could create an issue for some people and have a negative effect on them if the test said something bad. Face validity is good, but other validity techniques should be used above…

Tests need to be accurate (i.e. valid) for the researcher to know the test can be trusted. Tests have a concept or framework that guide what the test is supposed to measure. Construct-based validity evidence is used to measure to the degree that the test is measuring that construct. This type of validity has two subparts: discriminant validity and convergent validity. When constructs are not supposed to be related, discriminant validity checks to see if they are in fact unrelated. On the other…

and any variation and comparison procedures for all administered batteries (LaForte, McGrew, & Schrank, 2014). Furthermore, LaForte, McGrew, and Schrank (2014) states the WJ IV is based on the theoretical foundation from the Cattell-Horn-Caroll theory of cognitive ability and evidence to support the interpretation of the WJ IV, Validity Content was addressed using the master-test and cluster-content according to the CHC theory. The Content validity refers to the learning area measured by the…

Validity speaks to the magnitude to which the interpretations of test scores are grounded in theory and evidence. Validity is one of the most fundamental things to think about when evaluating psychological test. The question of validity can be expressed from three different perspectives, purpose of the test, the form the test comes in and the population being served. Therefore, researchers should never say “the test is valid.” Instead, researchers should state that the test is valid enough…

A panel of experts is needed to review the instrument, and determined the validity and reliability. The group discussion was an example of panel of experts, who determined the content of validity and reliability between the items composing in the instrument. The reliability was conducted before the expert panel review, which for this assignment were my classmates. The panel of experts provided suggestions with regard to improving the instrument’s readability (Sharma & Petosa, 2014). My…

Appendix B). Validity and Reliability An instrument is valid when it measures the construct it was designed for, and reliable when an instrument can consistently produce the same results over time, across different situations (Field, 2003). Content validity is an evaluation of the relationship between the items and the construct being measured (Cook & Beckman, 2006) and can be done in two ways. Firstly, a thorough revision of the construct would be required to avoid any ambiguities when…

new experiences will be formulated. However, initially only the relevant behaviour flexibility components sub score will be utilised. A detailed manual is provided which outlines among other things tests administration, procedure, scoring, norms, and reliability and validity. The standardised procedures for test administration replicates the standards of which the test was normed. Normative data was generated with a large and diverse sample and is provided for gender, age, job, and the…

Researchers address personality traits across different populations, including gender and age (Sutin, 2013). The quality of data associated with fact that structure personality traits show that African Americans and Whites are both above and below 125% of the federal poverty line and also those with higher and lower literacy rates. African-Americans have a bit higher percentage with the NEO-PI-R because they agree with items without fully understanding their content, but invalidity relates more…

control group is used to assess the validity of the battery, ensuring the scores baseline and follow-up scores are the same. Participants will be recruited as they are representative of the population being studied and the concussive circumstances in which will be specific to the area of study. Design Pre-test, post-concussion and follow-up measures will be assessed using the same cognitive tests. Two groups will be compared: a control group who do not sustain a concussion and an…

there is strong construct validity. By using the combination of instructional condition and time of test administration, the researchers are able to show the obvious differences between the experimental, standard treatment, and no treatment control groups. The use of each of these measures is designed to assess content knowledge as evidenced by test scores. The most obvious proof of the difference in conditions is the between pretest and posttest data, specifically for the video game with…
