Internal validity

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 test. In addition, the CHC theory and research were the “basis for the overarching test battery design blueprint” (LaForte, McGrew, & Schrank,…

Gensler: Divine Command Theory Gensler’s main argument for the Divine Command Theory is to argue the moral reasons for the existence of God. He gives the premises that everyone knows objective moral duties. Then comes the idea that if there are objective moral duties there has to be something that makes them moral law. For this the only answer that makes sense is God because it cannot be a person or other individuals in society since we do not have the authority to tell someone is they do…

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 hand, when constructs should be related, convergent validity checks to see if they are related. To assess both convergent and discriminative validity, the multi-trait…

0236566 In this squib, I criticize Norcross’ argument for the claim that Fred would still be acting immoral if he hired someone else to torture the puppies. I then argue that the second premise of Norcross’ target argument is false by providing an objection. My objection shows that there is a situation in which the action itself is immoral, but hiring someone to do it is not immoral. Now I will present Norcross’ target argument in standard form, for the claim that hiring someone else to torture…

Following the correct guidelines for significant figures is crucial in reporting accurate data that is reflective of the accuracy of the means used to collect it. It follows that the answer to any calculation can be no more nor any less precise than the least precise piece of data involved in the calculation. In this course, we will follow a set of rules meant to a) provide consistency to our significant figures and rounding and b) provide answers that agree, in accuracy and precision, with our…

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…

Differentiating Between Valid and Invalid Forms of Propositional Arguments Pages 164 – 175 of the textbook focuses on assessing valid forms versus invalid forms of propositional forms. It provides a brief description of what would be considered a valid argument and invalid argument. A valid argument passes the proper form test, while an invalid argument fails it. Five of the nine most used propositional arguments discusses are valid arguments. These valid forms include: the denying a disjunct,…

history of suicide attempt, past psychiatric hospitalization., history of physical or sexual trauma, current medical problems, history of hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrests (Jenelle Slavin-Mulford, External Validity of the Personality Assessment Inventory (PAI) in a Clinical Sample, 2012). The evetns were significant and scored as such because the degree of outcomes, categorized as positive (education, employment, or marriage), psychiatric severity…

will differ which is a limitation of the study. The primary analysis will be between control groups pre and post-test scores and experimental participant pre-test, post-concussion and follow-up test scores. The 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…

Arguments are when one offers a premise (or premises) to support a conclusion. Two main methods of support are joint and branching. Joint support is when related premises support the conclusion. On their own, each premise is not enough to constitute a valid argument for the conclusion so they have to work together in order for the conclusion to be reached. Branching support is when there are multiple, unrelated premises that lead to the same conclusion. These two types are very different but…
