The variance (σ2), is defined as the sum of the squared distances of each term in the distribution from the mean (μ), divided by the number of terms in the distribution (N).

Given a sample from a normal (or asymptotic normal) distribution, the sample variance is more often less than the population variance due to the skewed nature of the distribution of the unbiased sample estimate.

miskamm [114]

Answer:

The correct one is the definition of <u>community psychology</u>.

Explanation:

Community psychology studies how the environment affects individual and community functioning, that is, how the interdependence and interaction of individuals and groups with social, historical, cultural (and other) contexts influence social health. The purpose of community psychology is to prevent dysfunction while promoting wellness, empowerment and social justice. As we can see, this is the same as saying, "Community psychology aims to create healthy social and physical environments." Therefore, the definition of community psychology is correct.

On the other hand, the definition "Health psychology investigates how people grow and change across the life span" is incorrect. Health psychology is basically the study of how psychological, biological, cultural, and behavioral aspects influence health and illness.

Lunna [17]

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

Indeed, global warming has been in the foreground of politics and science for quite some time. There have been numerous studies conducted on the effects of global warming and what we might do to mitigate any threats. I think some policymakers are wary of the findings and some can trust that the conclusions are sound for the following reason.

Politicians are wary because, in reality, there are no 100% conclusive arguments that confirm that global warming is the result of humans. For other politicians, the evidence provided by environmental institutions is valid and they are prompt to proclaim that humans are to blame for global warming.

What is real, is that earth scientists think that global warming caused significant climate change in the past. And when they say the past, they mean a time before humans appeared on planet earth.

Climate change or global warming is not new for planet earth. It is a phenomenon that has happened in the past according to scientists and national agencies. It is believed that global warming had caused natural disasters such as the melting of ice caps and the flooding of many lands on Earth, destroying life forms.

That is why right now, many agencies are closely researching climate change. Among those institutions are the US National Academy of Sciences, the Geological Society of America, the American Meteorological Society, and the National Aeronautics and Space Administration.
