Concurrent validity

sample is a threat to the external validity of the study. It is important to note that this study does not represent a homogenous group. The sample is considered to be a convenience sample and cannot be echoed as a representative of the Latino immigrant community. Overgeneralization needs to be prevented because the sample does not represent an entire community. Therefore, the lack of generalization is a threat to external validity. However, the studies external validity can be adequate even if…

with the fact the media article does not tell us how the participants are being operationalized . External validity is low because of the lack of information on how the study was conducted. We did not know the operational definitions, conceptional definitions or the specific variables being studied, without that information how can one replicate the study to another sample. Conclusion validity is another cause for concern due to the fact the author of this media report did not state any big…

These are set issues that are always at heart of external validity, and that will set the tone for trustworthy results that can play a key role when sharing certain thoughts or opinions. Validity can be divided into two; external and internal validity. Internal validity refers to the consistency of variables at an internal level that whether the results represent the claims provided while external validity refers to evaluating a sample that is far away or not associated with sample…

A potential threat to the internal validity of my assigned research study is maturation because participants in the non-Snoezelen study were much older than other participants in the study with an age gap of up to 20 years. Maturation also threats internal validity in the sense that Snoezelen participants had been living in the residential aged care facility for a longer period of time compared to the non-Snoezelen group (Bauer et al., 2015). Participants who have been living in the residential…

ADHD, validity o Articles I narrowed down  Psychometric Properties of the Vanderbilt ADHD Diagnostic Parent Rating Scale in a Referred Population (Wolraich et al., 2003) • Internal consistency and factor structure = acceptable, consistent with DSM-IV • Good reliability  The Psychometric Properties of the Vanderbilt ADHD Diagnostic Parent Rating Scale in a Community Population (Bard et al., 2013) • Complicated statistics • Reasonable reliability, construct validity, criterion validity  Using…

development. These new mandates have generated significant challenges for states with respect to standards and test development; test validity; and accountability policy development and implementation (GAO, 2006; Zehr, 2006; Abedi, 2004; Crawford, 2002). There are several major concerns of English language proficiency assessments, first and foremost is the test validity, second the cultural bias of the assessments, third the nonstandard administration and fourth the assessment does not pair with…

this study, identify both a threat to internal validity and a threat to construct validity. In each instance, explain why the threat that you’ve identified is a threat and how significant a threat it is. King, Massoud and Song (2016), suffers from multiple validity threats of varying degrees of significance. Internal Validity As the principle-agent problem goes much of the way to explain the results of the paper, leaving a very serious internal validity concern for this paper. The authors’…

1. Name and describe at least 5 threats to validity (ea. threat accurately described is worth 2 points up to a possible 16 points). History threat- This occurs when the study outcome is affected by some historical event. If a specific event or chain of events does transpire during the time when a treatment is administered and it affects the observations it is a threat to the internal validity. Often times there is no way of determining if the historical event(s) or the treatment accounts for…

Research has stated that animals must be exposed and frequently involved in intense social interaction for facial recognition to occur. However, recent research has suggested that orangutans can differentiate between individuals with much less interaction required. The orangutans spend the majority of their time alone. It is estimated they spend 5% of their time associated in social situations. Additionally, very little is known about how the orangutans recognize faces in specific situations…

issue of generalizing results from WEIRD participants to other populations arises. As we learned in Dr. Cheung’s class, this privileged demographic represents only about 12% of the world’s population, therefore limiting the potential for external validity, as it is a non-representative sample. In discussing the recruitment of participants, this also calls into question their other method of recruiting test subjects: online advertisements. This recruitment led to sampling bias, in which some…
