External validity

However, negatively scored items were used sparingly (see 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…

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…

Reliability and Validity of Stress and Coping Styles Measurement Although extensive research has been conducted to analyze the factors influencing hopelessness depression (HD), there has been lesser research focused on the factors contributing to HD in adolescence. In “Daily stress and coping styles in adolescent hopelessness depression: Moderating effects of gender,” Rodriguez-Naranjo and Caño aimed to link daily stress and coping styles as factors contributing to HD in adolescence.…

assessment, I really focused on what we learned throughout the semester such as having a variety of question types, reaching more than one level of Bloom’s Taxonomy, straying from giving clues within my questions, and accounting for bias, reliability, validity, and diverse learners. I started out by choosing a lesson that would be a bit easier to put into a written test form (considering art classes are most commonly based on performance). So, I chose photography because there are a lot of…

general population), “treatment sample” (adolescents under treatment for alcohol use), and the “validation sample” (adolescents with psychological/behavioral problems). This wide range helps add to the data available when determining reliability and validity (Donlon,…

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,…
