Those who score above average on tests of mathematical aptitude are also likely to score above average on tests of verbal aptitude. According to Spearman, this best illustrates the importance of:
predictive validity
factor analysis
the g factor
reliability

80
90
100
110
Which of the following best describes Charles Spearman’s g of intelligence?
There are many factors that determine intelligence, but genetics is the most important one
The g is measured by the speed with which one can process information
A general intelligence that underlies success on a wide variety of tasks is g.
Giftedness is determined by both innate ability to perform and experiences one has in life.
IQ scores of today's better-fed and educated population exceed that of 1930's population
If a test designed to indicate which applicants are likely to perform the best on the job fails to do so, the test has
low reliability
low content validity
low criterion related validity
not been standardized
Carlos took an intelligence test and scored lower than he thought he should. He kept retaking the test, but he kept getting about the same score each time. This series of events indicates that the test was
reliable
standardized
valid
normed
Research finds that, in general, the higher an incoming college student scores on a given test,
the higher the student’s college grade point average (GPA). Which of the following best describes this
relationship?
positive correlation
negative correlation
bimodal distribution
skewed distribution
Which of the following is the best example
of fluid intelligence?

in the world without looking at a map
Identifying the author of a very famous
novel
Using cubes to figure out the solution
to a previously unseen puzzle

Dr. Collins is a cognitive scientist studying intelligence. His studies show that while many people are not good at math, they have a talent for fixing appliances such as cars. Dr. Collins's research supports the concept of
g
multiple intelligences
emotional intelligence
If Aaron’s intelligence quotient is 100, we know that he has a(n)
perfect score on a set of age-related tests
test performance superior to 90% of other children in the same age who took the test
average score
mental age below what is typical
According to the Stanford-Binet formula for an intelligence quotient (IQ), the IQ of a ten-year-old child with a mental age of eight and a half years is
85
95
100
115
Carla received a score of 100 on an IQ test. The mean for the test is 100 and the standard deviation is 15. Assume the test had a normal distribution of scores. Carla’s score on the test was equal to or greater than the scores of what percent of people?
50
68
84
15
Initially, intelligence quotients were calculated on the basis of a person’s mental and chronological ages. Using that approach, a person with a mental age of 12 and an intelligence score of 120 would have a chronological age of

The figure shows the distribution of scores on an intelligence test in the general population. As shown in the figure, the mean of the distribution is 100 and the standard deviation is 15. What percentage of the population has an IQ score above 145?
0.13%
2.27%
50%

The data shown in the graph depict which of the following?
Fluid intelligence
The improving validity of intelligence tests
The Flynn effect
The increased use of culture-fair tests
A researcher interested in finding a simple way to estimate intelligence decides to evaluate skull circumference as a possible indicator of intelligence. He finds that the size of an adult’s skull remains the same from one measurement to the next, but he finds that skull circumference is not a very good predictor of intelligence. In this example, skull circumference as a measure of intelligence is
reliable and valid
reliable but not valid
valid but not reliable
neither reliable nor valid
