Criterion validity

A study has shown that Internet appearance exposure and magazine reading exposure were correlated with higher internalization of thin ideals, appearance comparison, weight dissatisfaction, and drive for thinness in adolescent girls of mean age of 14.9 years. (Tiggemann & Miller, 2010). As mentioned in lecture, an average American watches 5.13 hours TV per day. (K.Dalrymple, personal communication, October 26,2015). This data shows that television is a dominant media that plays a great deal in…

There are two different groups of participants in the study who were chosen for the study arbitrarily. The goal of the study was to find the best way to help students learn better. The researcher chose to use quizzes that were given on a weekly basis. Since the quizzes are only a very small part of the students ' final grade, it is more logical to conclude that the investigator would use the exams that were given to the students as a better measure of student learning than their marks on the…

and whether or not “inappropriate elements are included in the indicator.” Although content validation is an “important contribution” to measurement validity, its chief limitation is that “alone it is incomplete, for two reasons”: “first, although a necessary condition, the findings of content validation are not a sufficient for establishing validity” and second “the trade-off between parsimony and completeness that arises because indicators routinely fail to capture the full content of a…

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…

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’…

In the United States, it is required by law that every child must attend school. This can be in the form of public or private schooling, along with homeschooling. If a parent knowingly does not enroll their child in school the consequences can be costly and can potentially result in jail time. Based on this information, it is very apparent that education is highly valued within the country. U.S. citizens are constantly looking for ways to improve their lives and education is essential to their…
