How Are Scores on IQ Tests Calculated?
Answer:

While people often talk about test scores, many
people are confused about exactly what these
test scores mean. In order to adequately assess
and interpret test scores,
psychometritians use a
process known as standardization. The
standardization process involves administering
the test to a representative sample of the entire
population that will eventually take the test. Each
test taker completes the test under the same
conditions as all other participants in the sample
group. This process allows psychometricians to
establish norms, or standards, by which individual
scores can be compared.
Intelligence test scores typically follow what is
known as a normal distribution, a bell-shaped
curve in which the majority of scores lie near or
around the average score. For example, the
majority of scores (about 68%) on the WAIS-III
tend to lie between plus 15 or minus 15 points
from the average score of 100. As you look
further toward the extreme ends of the
distribution, scores tend to become less common.
Very few individuals (approximately 0.2%) receive
a score of more than 145 (indicating a very high
IQ) or less than 55 (indicating a very low IQ) on
the test.
What Is Considered a High IQ?
The following is a rough breakdown of various IQ
score ranges. However, it is important to
remember that IQ tests are only one measure of
intelligence. Many experts suggest that other
important elements contribute to intelligence,
including social and emotional factors.

115 to 129 - Above average; bright
130 to 144 - Moderately gifted
145 to 159 - Highly gifted
160 to 179 - Exceptionally gifted
180 and up - Profoundly gifted

The term IQ, or Intelligence Quotient, generally
describes a score on a test that rates the
subject's cognitive ability as compared to the
general population.
IQ tests use a standardized
scale with 100 as the median score. On most
tests, a score between 90 and 110, or the median
plus or minus 10, indicates average intelligence. A
score above 130 indicates exceptional intelligence
and a score below 70 may indicate mental
retardation. Like their predecessors, modern tests
do take in to account the age of a child when
determining an IQ score. Children are graded
relative to the population at their developmental
level.
What is this cognitive ability being measured?
Simply put, IQ tests are designed to measure
your general ability to solve problems and
understand concepts. This includes reasoning
ability, problem-solving ability, ability to perceive
relationships between things and ability to store
and retrieve information. IQ tests measure this
general intellectual ability in a number of different
ways.
They may test:
spatial ability: the ability to visualize
manipulation of shapes
mathematical ability: the ability to solve problems
and use logic

language ability: This could include the ability
to complete sentences or recognize words when
letters have been rearranged or removed.

memory ability: the ability to recall things
presented either visually or aurally

Questions in each of these categories test for a
specific cognitive ability, but many psychologists
hold that they also indicate general intellectual
ability. Most people perform better on one type of
question than on others, but experts have
determined that for the most part people who
excel in one category do similarly well in the other
categories, and if someone does poorly in any one
category, he also does poorly in the others. Based
on this, these experts theorize there is one
general element of intellectual ability that
determines other specific cognitive abilities.
Ideally, an IQ test measures this general factor of
intelligence, abbreviated as g. The best tests,
therefore, feature questions from many categories
of intellectual ability so that the test isn't
weighted toward one specific skill.
Because IQ tests measure your ability to
understand ideas and not the quantity of your
knowledge, learning new information does not
automatically increase your IQ. Learning may
exercise your mind, however, which could help
you to develop greater cognitive skills, but
scientists do not fully understand this
relationship. The connection between learning and
mental ability is still largely unknown, as are the
workings of the brain and the nature of
intellectual ability. Intellectual ability does seem
to depend more on genetic factors than on
environmental factors, but most experts agree
that environment plays some significant role in its
development.
But can you increase your IQ score? There is
some evidence that children develop higher
intellectual ability if they receive better nurturing
and diet as babies, and a higher degree of
intellectual stimulation in preschool tends to
boost children's IQ scores for a few years of
elementary school but does not permanently
increase IQ scores. For the most part, adult IQ
scores don't significantly increase over time.
There is evidence that maintaining an
intellectually stimulating atmosphere (by learning
new skills or solving puzzles, for example) boosts
some cognitive ability, similar to the way
maintaining an exercise regimen boosts physical
ability, but these changes aren't permanent and
do not have much effect on IQ scores.
So your IQ score is relatively stable, no matter
what education you acquire. This does not mean
that you can't increase your intelligence . IQ tests
are only one imperfect method of measuring
certain aspects of intellectual ability. A lot of
critics point out that IQ tests don't measure
creativity, social skills, wisdom, acquired abilities
or a host of other things we consider to be
aspects of intelligence. The value of IQ tests is
that they measure general cognitive ability, which
has been proven to be a fairly accurate indicator
of intellectual potential. There is a high positive
correlation between IQ and success in school and
the work place, but there are many, many cases
where IQ and success do not coincide.

Local intilligence test

nairalander:
your reply or contribution to any topic you read shows your level of intilligence
while some ppl just don't know how to put down Their ideas,others na follow follow ppl fir Their thread.
Funny: I come across sm1 profile in nairaland that Have more than 2000 ppl she is following whithout any post since she register in 2008

Intelligence has been an important and
controversial topic throughout psychology's
history. In addition to questions of exactly how to
define intelligence, the debate continues today
about whether it can be accurately measured.
While psychologists often disagree about the
definition and causes of intelligence, research on
intelligence plays an important role in many areas
including policy decisions regarding how much
funding should be given to educational programs,
the use of testing to screen job applicants and
the use of testing to identify children who need
additional academic assistance.
The term "intelligence quotient," or IQ, was first
coined in the early twentieth century by a German
psychologist named William Stern. Since that
time, intelligence testing has emerged as a widely
used tool that has led to the development of
many other tests of skill and aptitude. However, it
continues to spur debate and controversy over
the use of intelligence tests, cultural biases,
influences on intelligence and even the very way
we define intelligence.
In order to gain a deeper understanding of
intelligence and the tests that have been
developed in an attempt to measure this concept,
it is important to understand the history of
intelligence testing, the scientific research that
has been conducted and the findings that have
emerged.

I know something like this of Great learning and knowledge wil not get to front page, but if its topic that's nt conclusive the mods wil take it fp .

abeg make una recommend it to fp nairalander

I wish say seun go do iq test for all d mods in all section for the kind topic they bring to front page

for a Long time I hv nt said what I believe, nor do I ever believ what I say and if indeed sometimes I do happen to tell the truth, I hide it among so many lies that it is hard to find.

@OP....Wetin be dis? Are you chatting with yourself? O ga o.

sholay2011: @OP....Wetin be dis? Are you chatting with yourself? O ga o.

u dey here or u dey waka pass as other do
I think say ppl dnt know the meaning of iq test.
so I decided to do a litle mental chat as u say

the level of your understanding to some knowledge and skills of works show how adaptative and level of your iq

my own way of calculation of Intelligence quotient is how constructive I am in craft and words line rememberance after a Long time

but am nt good in remembering faces I hv meet after a Long time except I meet them in same place or event or Introduction from the person wil recall my memory.
