Convergent validity

The plate tectonic theory was developed in the 1960’s and it is extremely important to have a fond understanding of as it is an explanation of the amazing scientific feats that have happened and are still happening in our world today. For example, it explains why the land we stand on is in its place, how volcanoes, tsunamis and mountains are formed and many more scientific phenomenon. This theory is that the outer shell of Earth is separated into multiple plates, which are floating on the mantle…

One location where the earth will be different from now is the Andean Volcanic Belt. This group of volcanoes are located near the western coast of South America, near the Andes mountains. From the Volcano Map, it can be seen that there is a large array of volcanos in certain spots of western South America. I believe that this particular formation will continue to form more and more volcanos as time goes by. This would most likely happen because of the subduction boundary going on (South American…

Mid ocean ridges is the creation of the motion diverging plates and it is an underwater mountain range which are formed by plate tectonics. It consist of mountains linked together, having a valley running along the spine, and its known as an oceanic spreading center which is in charge of the seafloor spreading. New seafloor is being produced when convection currents rise in the mantle layer which is under the oceanic crust, it then create magma that cools down into basalt where two plates is…

karen Plate Tectonics There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth…

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…
