Ecological 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…

The hard-core of neoclassical economic theory has been criticized, it constructed a protective belt that helped adjusts the main ideas. The protective belt theory includes environmental economics that help keeps the strong core of neoclassical economics. It explains the hard-core of the neoclassical economic research program and protects it from negative heuristic attacks. Environment economic seeks to find how the environmental impacts the economy, which leads to the decisions rational people…

I believe the solution lies within the concept of “Living with Less” (LwL). The “LwL” approach to life offers people affordable housing, the ability to become debt-free or minimize their living expenses, and the opportunity to leave a smaller ecological foot print on the Earth. Adopting the “LwL” philosophy will allow everyone to do their part to help maintain resources, be less wasteful, and ensure there is still enough for generations to come. Americans collectively have had the same…

Australia, Malaysia and various other areas around the world. This eBook was published in 2009 and was presented at the SB07 NZ Conference in 2009. Due to the research being fairly aged the statistics may not hold the same level of reliability and validity as it did in 2009. However, the information provided was very informative and understandable. The research set a good starting point to understanding the effects of New Zealand’s water usage. Although the case study that the eBook is based off…

Sustainability is concerned with the promoting of the most effective use of resources, the protection of the environment and ecosystems and the development of a more equitable world society. As sustainability includes different issues, is often difficult to define precise terms of it. Considering the Venn diagram, sustainability can be described as the intersection of three main issues as environmental, economic and social issues. Sustainability Venn diagram…

(how far the ecosystem can support a population before being damaged) of the environment. Balancing liveability with sustainability can be a difficult task, especially when those who grant you power expect a better quality of life along a smaller ecological footprint. This is the purpose of the smart growth principles - principles that promote the urban planning and development theories that prevent urban sprawl - to enhance quality of life, to preserve the natural environment, and to…
