Question 1

If you score at the 50th percentile on an intelligence test,this means that your IQ is

Accepted Answer

The 50th percentile means that you have performed better than 50% of the population and worse than the other 50%. In terms of IQ, the average score is 100, so scoring at the 50th percentile would also mean that your IQ is 100. Therefore, the correct answer is D.

Question 2

The measurement of a person's score on an intelligence test relative to others taking the same test is called a

Accepted Answer

Deviation IQ is the measurement of a person's score on an intelligence test relative to others taking the same test, expressed as the number of standard deviations the score is above or below the mean score. Mental age (A) is a score based on the average abilities of individuals at a certain age level. Chronological IQ (B) is not a commonly used term in intelligence testing. Multiple IQ (D) is not a recognized term in intelligence testing.

Question 3

When one's mental age is lower than one's actual age in years,then

Accepted Answer

Mental age is a measure of intelligence level based on the average age at which people achieve certain intellectual milestones. If someone's mental age is lower than their actual chronological age, that suggests they have lower than average intelligence, which would correspond to an IQ score below 100. Therefore, the best choice is B.

Question 4

A deviation IQ represents a person's

Accepted Answer

A deviation IQ is a way of standardizing a person's raw score on a mental test by comparing their performance to the average performance of others in their age group. The resulting score is a measure of the person's relative standing in the group, with a score of 100 indicating average performance and higher scores indicating above-average performance. Therefore, choice D is the correct choice as it reflects the relative standing based on mental test performance.

Question 5

If Tomas's intelligence quotient is 115,we know that

Accepted Answer

An intelligence quotient of 115 indicates that Tomas's mental age is greater than his chronological age. IQ scores are based on a comparison of a person's performance on an intelligence test to the performance of others in their age group, so a score of 115 means that Tomas performed better than the average person of his age. Therefore, his mental age is higher than his chronological age.

Question 6

If you score at the 50th percentile on an intelligence test,this means that

Accepted Answer

The 50th percentile represents the point at which half of the people who took the test scored higher than you and half scored lower than you.

Question 7

If you score at the 97th percentile on an intelligence test,this means that your IQ is

Accepted Answer

The 97th percentile indicates that you scored better than 97% of the population who took the test. This translates to an IQ of around 130, which is considered above average intelligence. Therefore, the correct option is C.

Question 8

If Jane's intelligence quotient is 100,we know that she has a

Accepted Answer

An intelligence quotient (IQ) of 100 indicates that the individual's mental age is typical of their chronological age. This means that Jane's cognitive abilities are at the level that is expected for someone of her age. While options A, B, and C indicate that Jane's abilities are either below or above average, which is not reflective of an IQ score of 100.

Question 9

The distribution of IQ scores

Accepted Answer

The normal or bell-shaped curve is the most commonly observed distribution of IQ scores, with most of the scores falling in the middle (around 100) and fewer scores at each end. This distribution is also referred to as a Gaussian distribution. Option A describes a bimodal distribution, while options B and C specify restricted ranges of IQ scores, which are not representative of the entire population's distribution.

Question 10

When one's mental age is higher than one's actual age in years,then

Accepted Answer

A higher mental age than actual age suggests a higher IQ, as mental age is a measure of intellectual ability in comparison to typical peers at a certain age. Therefore, the best choice is C. The other options are not related to the given information.

Question 11

The average seven-year-old child with an IQ of 100 has a mental age of

Accepted Answer

IQ is calculated as (mental age/chronological age) x 100. For a seven-year-old with an IQ of 100, the mental age is the same as the chronological age, which is seven.

Question 12

A 12-year-old child with an IQ of 100 would have a mental age of

Accepted Answer

Mental age is calculated by comparing an individual's cognitive abilities to the average abilities of individuals in a specific age group. An IQ score of 100 is considered average for any age. Therefore, a 12-year-old child with an IQ score of 100 would have a mental age that matches their chronological age, which is 12.

Question 13

If you score at the 84th percentile on an intelligence test,this means that your IQ is

Accepted Answer

Scoring at the 84th percentile means that you performed better than 84% of the population who took the same test. The average IQ is typically set at 100, and scoring at the 84th percentile corresponds to an IQ score of approximately 115. Therefore, the correct answer is C.

Question 14

When one's mental age is the same as one's actual age in years,then

Accepted Answer

IQ is calculated based on the ratio of mental age to chronological age, multiplied by 100. If mental age is the same as chronological age, the ratio is 1:1, and therefore the IQ score is 100, which is considered average.

Question 15

An IQ of 100 is considered _______ intelligence.

Accepted Answer

An IQ of 100 falls within the average range of intelligence. Scores between 90-109 are considered average on the IQ scale.

Question 16

Average intelligence is usually defined as any score from

Accepted Answer

The average intelligence quotient (IQ) is usually defined as any score between 90 and 109. This is based on the standard deviation of IQ scores, which is set at 15 points. Therefore, scores falling within one standard deviation of the mean IQ score (100) would be considered average.

Question 17

If you take an IQ test today,the test examiner will convert your relative standing on this test for your age group to a __________ IQ.

Accepted Answer

IQ scores are typically based on the deviation IQ system, which compares a person's score with the scores of others in the same age group. This system allows for a more accurate assessment of a person's intellectual ability, as it takes into account the natural variation in intelligence within different age groups. The result is a score that represents a person's standing relative to others in their age group, with an average score of 100 and a standard deviation of 15 points.

Question 18

Which of the following is obtained statistically from a person's relative standing in his or her age group and expresses how far above or below average the person's score was in comparison to the other scores?

Accepted Answer

Deviation IQ is obtained statistically from a person's relative standing in his or her age group and expresses how far above or below average the person's score was in comparison to the other scores. Ratio IQ compares the mental age to chronological age, while mental age and chronological age are not obtained statistically but rather measured through testing and observation.

Question 19

Jorge's chronological age is nine,and his mental age is 11.His IQ is

Accepted Answer

The answer of Jorge's chronological age is nine,and his mental...

Question 20

If Suke's intelligence quotient is 85,we know that

Accepted Answer

An IQ of 85 indicates that Suke's mental age is less than her chronological age, as IQ is calculated by dividing mental age by chronological age and multiplying by 100.
