Answer:This would be an example ofa. snowball sampling
Explanation:
A participant chooses someone else to participate on their behalf in a study or test. This happens in cases where it is not easy to fin the actual potential participants. It is called a snowball because when you roll a ball in an snpw it keeps attaching more snow until it gets bigger. The sampling is done randomly which means it is a non probability sampling
Snowball sampling consists of two steps:
The researcher will choose potential participants which are only few at the beginning. The chosen participants will recruits more participants, they don't have to give names. This recruitment goes on until the desired sample proportion is reached. The participants will only encourage others to come but that is not forced. It can be ethically challenging because subjects can be of sensitive topics
Why is Snowball Sampling Used?
In cases where a research deals with sensitive topics such as cheating, shoplifting, drug use and other deviant societal behaviours, participants may not feel comfortable to come forward. However they may suggest others in similar situation as them and be assured of confidentiality.
Answer:
Electoral vote is the choice expressed collectively by the electoral college, which determines the winner of elections for president and vice president
The scaffolding theory of the cognitive aging-revised (STAC-r) model suggests that the reason older adults continue to perform at high levels despite neuronal deterioration is because of compensatory scaffolding.
<h3 /><h3>Scaffolding Theory of Cognitive aging-revised</h3>
- Throughout the lifespan, brain dynamics are characterized by a process called scaffolding. It is the brain's typical reaction to difficulty, not just the brain's natural aging process.
- Young adults' brains' reactions to learning unfamiliar skills have been described in terms of the scaffolding theory of cognitive.
- The Scaffolding Theory of Cognitive Aging (STAC), a contemporary theory that aims to lessen the effects of aging-related cognitive decline, contends that functional changes with aging are a result of a lifelong process of compensatory cognitive scaffolding.
- According to STAC, the brain is a dynamically adaptable structure that ages in both beneficial and detrimental ways.
