You are a school psychologist who administers the Wechsler Intelligence Scale for Children (WISC) to all sixth graders before th

ey enter into junior high. You notice that the intelligence scores have a smaller standard deviation than when you administer the WISC to children in your consulting practice. Why?

Because intelligence scores are a general test for people, so the scores produced might be similar. Whereas the Wechsler Intelligence Scale for Children (WISC) is more focused on children, so the scores obtained will be more diverse.

<h2>Further Explanation </h2>

Intelligence Quotient (IQ) is the total score obtained from a series of standardized tests designed to assess human intelligence. The abbreviation "IQ" was coined by psychologist William Stern for the German term Intelligenzquotient, the term for assessment methods for intelligence tests at the University of Breslau which he suggested in the 1912 book.

Historically, IQ is a score obtained by dividing a person's mental age score, obtained by conducting an intelligence test, based on a person's chronological age, both expressed in years and months. The resulting fraction (quotient) is multiplied by 100 to get an IQ score. For modern IQ tests, the standard normed sample mean score is defined as IQ 100 and the score of each standard deviation (SD) up or down is defined as 15 IQ points greater or less. According to this definition, about two-thirds of the population score is between IQ 85 and IQ 115. About 2.5 percent of the population score is above 130, and 2.5 percent is below 70.

The score from an intelligence test is an estimate of intelligence. Unlike, for example, distance and mass, a measure of concrete intelligence cannot be achieved given the abstract nature of the concept of "intelligence". IQ scores are related to factors such as morbidity and mortality, parental social status, and, to a large extent, biological parental IQ. While IQ heritability has been investigated for almost a century, there is still debate about the importance of heritability estimation and inheritance mechanisms.

The Wechsler Intelligence Scale for Children (WISC), developed by David Wechsler, is an individually-managed intelligence test for children between the ages of 6 and 16. The Fifth Edition (WISC-V; Wechsler, 2014) is the latest version.

WISC-V takes 45-65 minutes to manage. This results in a Full-Scale IQ (previously known as intelligence quotient or IQ score) that represents a child's general intellectual abilities. It also provides five primary index scores: Verbal Understanding Index, Visual-Spatial Index, Fluid Reasoning Index, Working Memory Index, and Processing Speed ​​Index. These indices represent the ability of children in the discrete cognitive domain. Five additional composite scores can be derived from various combinations of primary or primary and secondary subtitles.

Five complementary substitutions produce three complementary composite scores to measure cognitive abilities related to the assessment and identification of certain learning disabilities, specifically dyslexia, and dyscalculia. Variations in testing procedures and objectives can reduce assessment time to 15-20 minutes for a single primary index assessment, or increase testing time to three hours or more for a complete assessment, including all primary, supplementary, and complementary indices.

Explanation:

What is standard deviation?

According to Oxford dictionary this is a quantity which expresses how different members of a group are to the mean value.

If there is not much diversity there won't be much standard deviation within the school.

Viktor [21]

Answer:

Option B

Explanation:

NCAA Stands for "National Collegiate Athletic Association which is responsible for banning schools from participating in sports for at least a year.

The death penalty is the harshest form of penalty it can give, and most of this punishment result in schools not competing in sports for the duration of the death penalty.

How does geography help or hinder Human development?
Katyanochek1 [597]
<h3>Answer: one of the most important factors in development is geography, where the country is in the world, and climate. It's no coincidence that the poorest countries are in the tropics, where it is hot, the land is less fertile, water is more scarce, where diseases flourish... Some countries are just at a natural disadvantage.</h3><h3> </h3><h3></h3>

Explanation: Geography affects human development by

  • vegetation
  • climate
  • local water cycle
  • land formations                                  

Geography doesn't just determine  whether humans can live in a certain area or not, it also determines people's lifestyle, as they adapt to the available food and climate patterns.

Domestication and pastoralism were key aspects in the development of the
Tatiana [17]

Answer: The school board wants you to answer C) Agricultural Revolution, but that is incorrect.

The correct answer would be during the Neolithic Era, so none of the choices would be the right answer.

Explanation: During the Paleolithic Era, which corresponds to the old stone age, people were hunter-gatherers.  This means that they obtained food by hunting animals and by gathering fruits, vegetables, and nuts from local plants.  So options A and B are pretty much the same thing and incorrect.

Domestication and pastoralism developed during the Neolithic or new stone age when people discovered that, if they took care of certain plants, they would grow again and give them more food.  Domestication is not the same thing as agriculture (even though the school system continues to teach it this way).

The Agricultural Revolution actually refers to a much later period in history, during the 18th century in Britain, when traditional agriculture went through a process of transformation.  This is way after domestication and pastoralism.  

Finally, option D is also incorrect because classical civilizations like Greece and Rome already had full-scale agriculture and had already gone through the process of domestication and pastoralism.
