Ecological validity

The next validity to check would be the external validity. The definition of external validity by Paul C. Cozby and Scott C. Bates (2015), in their book Methods in Behavioral Research would be to see if the study can be generalized and applied to other populations. The study was mostly conducted on Caucasians, however, the studied would still be able to be applied to others since it is dealing with the effects of parenting which can be applied to all (Cozby & Bates 2015). The final validity is…

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,…

401 teachers across the US. Kourmousi, Darviri, Varvogli, & Alexopoulos (2015) adapted the TSI to a Greek version and ran a comparison against the Perceived Stress Scale in which they were able to obtain similar results as well as show convergent validity in a group of 3.447 teachers. Individual influences on reliability might be how Laney is experiencing her life right now, she is having trouble focusing which may cause her to misunderstand questions or rate them inappropriately. The rater…

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…
