Question 1

Melinda completed the Computer Programming Aptitude Test when she applied for a position with Beta Electronics.Six months later,she took the same test when she applied for a position with another company.The fact that her scores were almost identical on the two occasions suggests that the test has a high degree of

Accepted Answer

If Melinda's scores on the test were almost identical on two different occasions, it suggests that the test has a high degree of reliability, meaning it consistently provides accurate results. Correlation refers to a relationship between two variables, while predictive validity measures how well a test predicts future performance. Standardization ensures that a test is administered consistently to different individuals.

Question 2

When Brandon was told that he correctly answered 80 percent of the items on a math achievement test,he asked how his performance compared with that of the average test-taker.Brandon's concern was directly related to the issue of

Accepted Answer

Brandon's concern about how his performance compared with that of the average test-taker suggests he is concerned with the standardization of the test, or how the test is normed and scores are interpreted.

Question 3

An increase in average intelligence test performance during the past decade would best illustrate why intelligence testing requires up-to-date

Accepted Answer

An increase in average intelligence test performance over time suggests that the test norms and standards may need to be updated or revised, which requires regular standardization to maintain the accuracy and reliability of the test results. Validity tests, reliability indices, and processing speed estimates are also important components of intelligence testing but are not directly related to the need for up-to-date standardization.

Question 4

A test that measures or predicts what it is supposed to is said to have a high degree of

Accepted Answer

Validity refers to the extent to which a test measures or predicts what it is supposed to measure or predict. Standardization refers to the process of establishing norms and uniform procedures for administering and scoring a test. Reliability refers to the consistency or stability of a test over time or across different raters. The g factor refers to the general intelligence factor that underlies all mental abilities.

Question 5

Academic aptitude test scores are MOST likely to predict accurately the academic success of ________ students.

Accepted Answer

The answer of Academic aptitude test scores are MOST likely...

Question 6

The distribution of intelligence test scores among ________ Americans is represented by the normal curve.

Accepted Answer

Intelligence test scores among all Americans, regardless of race or ethnicity, follow a normal curve. While there may be differences in average scores or the shape of the curve among different groups, the distribution itself is still normal.

Question 7

A measure of intelligence based on head size is likely to have a ________ level of reliability and a ________ level of validity.

Accepted Answer

The answer of A measure of intelligence based on head...

Question 8

If a test is standardized,this means that

Accepted Answer

Standardized tests are designed to be administered and scored consistently, using pre-established procedures, to ensure that a person's test performance can be compared with that of a representative pretested group. This allows for meaningful interpretation of test scores and can help identify strengths and weaknesses in a person's abilities. Standardized tests may also be designed to measure specific aspects of performance, and they often yield consistent results when administered on different occasions. However, the fact that a test is standardized does not necessarily guarantee that it accurately measures what it is intended to measure or that most test scores will cluster near the average.

Question 9

The normal curve would represent the distribution of

Accepted Answer

The normal curve is used to represent a distribution of continuous numerical data that is normally (or approximately normally) distributed, such as height, weight, or IQ scores. Therefore, option C is the best choice as it involves the physical heights of a group (American women). Option A and B are not suitable as they do not involve continuous numerical data, and option D is too broad and general.

Question 10

Dr.Wie assesses the correlation between scores obtained on two halves of his new test to measure a person's ability to make interracial facial identifications.He is checking the ________ of his new test.

Accepted Answer

Dr. Wie is checking the correlation between scores obtained from two halves of the test, which is an indicator of test-retest reliability. Therefore, the best choice is A) reliability. The other options, validity, norms, and variability, are not directly related to assessing test reliability through the correlation of scores obtained from two halves of a test.

Question 11

Researchers assess the correlation between scores obtained on two halves of a single test in order to measure the ________ of the test.

Accepted Answer

The correlation between scores obtained on two halves of a single test measures the consistency or stability of the test over time, and this is known as the test's reliability. Therefore, option B is the correct choice. Option A (validity) refers to the degree to which a test measures what it is intended to measure, and the information given does not indicate that this is being assessed. Options C (standardization) and D (normal distribution) are not relevant to this concept of assessing the correlation between scores on the two halves of a test.

Question 12

About ________ percent of WAIS scores fall between 85 and 115.

Accepted Answer

This question is asking about the percentage of scores falling within one standard deviation of the mean on the WAIS. In a normal distribution, approximately 68% of scores fall within one standard deviation of the mean. Therefore, the correct choice is C, 68%.

Question 13

Piper is taking an intelligence test that provides a single score,while Taylor is taking a test that has separate scores for four different categories of questions.Piper's test is the ________,and Taylor's is the ________.

Accepted Answer

The Stanford-Binet test provides a single score, while the WAIS (Wechsler Adult Intelligence Scale) has multiple subtests that measure various cognitive abilities. The WISC (Wechsler Intelligence Scale for Children) is also a test with multiple subtests, but since the question specifies that Piper is an adult, it is more likely that she will take the WAIS. Thus, Piper's test is likely the WAIS and Taylor's test is likely the Stanford-Binet.

Question 14

The distribution of intelligence test scores in the general population forms a bell-shaped pattern.This pattern is called

Accepted Answer

The bell-shaped pattern described in the question is a characteristic of a normal distribution, also known as a normal curve. Option A refers to a group of individuals used to establish norms, option B refers to a measure of consistency, and option C refers to a statistical technique used to identify underlying factors in data. Therefore, the answer is D - a normal curve.

Question 15

The test Vincente is taking includes questions such as "In what way are brass and steel alike?" Vincente is taking the

Accepted Answer

The WAIS (Wechsler Adult Intelligence Scale) includes questions that assess similarities, which is a type of question that asks test-takers to identify how two things are alike, fitting the description given.

Question 16

To find out if her new spatial reasoning test is good at measuring what it was designed to measure,Dr.Chu compares the scores on her test with the scores and grades of college students enrolled in courses that involve spatial reasoning.In this instance,Dr.Chu is in the process of

Accepted Answer

Dr. Chu is comparing the scores on her test with the scores and grades of college students enrolled in courses that involve spatial reasoning to determine if her test is measuring what it was designed to measure. This is an example of establishing the test's validity. Reliability refers to the consistency of test scores, while standardization refers to the process of administering and scoring a test in a consistent and uniform manner. Conducting a factor analysis of the test involves examining the underlying factors or dimensions of the test.

Question 17

Block design puzzles are used in one of the subtests of the

Accepted Answer

Block design puzzles are part of the Performance IQ portion of the Wechsler Adult Intelligence Scale (WAIS).

Question 18

Psychologists would calculate the relationship between intelligence test scores and school grades in order to assess the ________ of the intelligence test.

Accepted Answer

The relationship between intelligence test scores and school grades is a measure of the predictive validity of the intelligence test. This assesses how well the test is able to predict future performance in a related domain. The other options are not relevant in this context - reliability is about consistency of scores, standardization is about ensuring consistent administration of the test, and normal distribution refers to the distribution of scores in a population.

Question 19

Intellectual disability was formerly referred to as

Accepted Answer

Intellectual disability was formerly referred to as "mental retardation" until the term was replaced with a more appropriate and respectful language.

Question 20

If a test yields consistent results every time it is used,it has a high degree of

Accepted Answer

A test that yields consistent results every time it is used has high reliability. Reliability refers to the consistency or stability of a measure or test over time, across different raters, and in different testing situations. Standardization refers to the process of ensuring that test administration and scoring are consistent and uniform for all test-takers. Predictive validity refers to the ability of a test to predict future performance or outcomes, and correlation refers to the degree of association between two variables. While these concepts may be related, they are distinct from reliability.
