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 measurementto 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 but not valid

1:1
In a normal distribution of test scores, the percentage of scores that fall at or below the mean score is
50
A psychologist has just developed a new test that he hopes will be a good measure of intelligence. At the surface level, the questions appear to be the types of puzzles and problems that would provide an intellectual challenge and give insight into someone's intellectual abilities. Unfortunately, when he distributes the test to a classroom of college students, it does not appear to perform similarly to existing measures of intelligence. The test does not predict student GPAs and in fact is better at predicting performance on a measure of anxiety than intelligence. Which of the following characteristics does the new intelligence test possess?
Face validity, because the test looks like it should measure intelligence.
Which of the following methods is used in studies designed to determine the primary components of intelligence?
Factor analysis

Dr. Sosa administers the first exam to all his introductory psychology students, which amounts to 250 students total. The mean for the first exam was 75%. The grades for Dr. Sosa's classes are distributed as shown below.
The distribution is positively skewed.
The Psychology Aptitude Test (PAT) was administered to incoming college psychology majors. Their scores were later compared to their performance in the introductory psychology course, and high scores on the PAT were related to high grades in the course. Therefore, the PAT has
The performance of the group on which an IQ test is standardized sets the
Which of the following is the best example of fluid intelligence?
Using cubes to figure out the solution to a previously unseen puzzle
Charles Spearman's concept of g is most accurately defined as
a single, underlying intellectual capacity measured by intelligence tests
Average IQ scores have increased steadily over the past 100 years. It has been argued that this effect is most likely due to
an increase in the average number of years in school
A test that is valid must
be reliable
The intelligence quotient (IQ) has traditionally been based on the relationship between an individual's mental age and his or her
chronological age
A teacher creates a test that will predict how well a student will do as a commercial airline pilot. The test is taken before the training, and then the teacher correlates the test score to the number of safe flying hours. The teacher is trying to determine whether the test has
criterion-related validity
A normally functioning 65-year-old who cannot solve abstract logic puzzles as quickly as he did when he was younger is experiencing a
decrease in his fluid intelligence
A female student was rejected by a college because her score on a test used by the college to predict performance there was below the college's cutoff score. An influential alumnus of the college intervened on the student's behalf and the student was admitted. Four years later the student graduated with honors. The most likely explanation of this outcome is that the test
had less than perfect validity
A disadvantage of using Alfred Binet's concept of mental age in assessing intelligence is that
it is inappropriate for adults
A standardized test must have all of the following EXCEPT
multiple-choice questions
Alfred Binet's efforts to measure intelligence were directed at
predicting children's success in school
A test is administered to 1,000 fourth graders across the country, and then it is readministered to the same children 90 days later. The test-retest results will yield an evaluation of the test's
reliability
The correlation between scores obtained on two halves of a single test yields information about the test's
reliability
Henry 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
If students get approximately the same score on the second administration of a test as they did on the first, then the test is
reliable
On individual intelligence tests such as the Stanford-Binet and Wechsler scales, an IQ of 100 indicates that the test taker
scored at the average level for test takers of the same age
A student who obtained a percentile rank of 75 on an achievement test is best characterized as having
scored higher than 75% of the test takers
A student's test score of 86 is at the 42nd percentile. This means that this student has
scored the same as or higher than 42 percent of her fellow students
Malik completed a personality test in January, again in May, and once more in September. His three scores were very similar to one another. This similarity suggests that the test has
