Question 1

In a normal distribution of scores,approximately what percent of the z-scores will be negative?
A)0
B)25
C)50
D)Cannot determine from the information given.

Accepted Answer

In a normal distribution, approximately 50% of the z-scores will be negative because the mean (which is the center of the distribution) is assigned a z-score of 0, and approximately half of the scores will fall to the left of the mean. This is because the normal distribution is symmetric, meaning that the shape of the distribution to the left of the mean is a mirror image of the shape to the right of the mean. Therefore, approximately 50% of the z-scores will be negative.

Question 2

Sam,a seventh grader,received a grade-equivalent score of 9.2 on a standardized vocabulary test at the end of the spring term.This result indicates that Sam
A)achieved about the same level as the average ninth graders in the norms group.
B)knows as much vocabulary as the typical ninth grader in the norms group.
C)scored above average compared to seventh graders in the norm group.
D)should be awarded a grade of A for his achievement in vocabulary.

Accepted Answer

The answer of Sam,a seventh grader,received a grade-equivalent score of...

Question 3

In a normal distribution,which one of the following measures of central tendency will have the highest value?
A)Mean
B)Median
C)Mode
D)The central tendencies will be equal.

Accepted Answer

In a normal distribution, the mean, median, and mode are all equal, so none of them will have a higher value than the others.

Question 4

A percentile rank score of 70 means that the student
A)answered a majority of the questions correctly.
B)had 70 correct answers on the test.
C)scored as well as or better than 70 percent of all the test-takers.
D)scored at the seventh-grade level compared to other students.

Accepted Answer

A percentile rank score of 70 means that the student scored as well as or better than 70 percent of all the test-takers. It has nothing to do with the number of correct answers, grade level comparison or a majority of correct answers.

Question 7

The Public Speaking Aptitude Test (PSAT)scores are reported for four students from their respective high schools.However,different standard scores were reported for each.Assuming that all scores were based on a raw score normal distribution,which student has the highest score?
A)Angie: T-score = 57
B)Bart: z-score = +1.33
C)Kris: stanine = 5
D)Larry: SAT-type score = 550

Accepted Answer

A z-score of +1.33 indicates that Bart's score is 1.33 standard deviations above the mean, which is typically higher than the other types of scores listed.

Question 8

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15.Based on properties of the mathematical normal curve,which one of the following statements is TRUE?
A)Approximately 90 percent of the scores fall between 85 and 115.
B)A score of 70 is equally as probable as is a score of 130.
C)There are more scores above 130 than below 85.
D)There are more scores above the mean than below the mean.

Accepted Answer

A score of 70 and a score of 130 are both 2 standard deviations away from the mean (100), making them equally probable in a normal distribution.

Question 9

In a normal distribution,a T-score of 60 is equal to approximately what percentile rank?
A)60
B)84
C)95
D)99

Accepted Answer

A T-score of 60 is one standard deviation above the mean in a normal distribution, which corresponds to approximately the 84th percentile.

Question 10

In a normal distribution,the type of derived score that has unequal units is ________.

Accepted Answer

The answer of In a normal distribution,the type of derived...

Question 11

What score-reporting method decreases competition among students by representing the widest range of raw scores?
A)Percentile ranks
B)Stanines
C)T-scores
D)z-scores

Accepted Answer

The answer of What score-reporting method decreases competition among students...

Question 12

Assuming that the raw scores are distributed normally,which one of the following standard scores indicates the best performance relative to the group being tested?
A)Percentile rank of 60
B)Stanine score of 8
C)T-score of 59
D)z-score of +.76

Accepted Answer

A stanine score of 8 is considered to indicate above-average performance, placing an individual in the top 4% of the population. In comparison, a percentile rank of 60 indicates that the individual performed better than 60% of the population, a T-score of 59 only indicates a performance better than around 79% of the population, and a z-score of +.76 only indicates a performance better than around 78% of the population. Therefore, the stanine score of 8 is the best indicator of high performance relative to the group being tested.

Question 13

Molly is preparing to take a standardized test that will be used by administrators to evaluate the type of school placement she should have.What type of assessment is Molly involved in?
A)Criterion-referenced
B)High-stakes testing
C)Norm-referenced
D)Standardized aptitude testing

Accepted Answer

High-stakes testing is a type of assessment that has significant consequences for the individual being tested. In this case, the test will be used to determine Molly's school placement, which is a high-stakes decision.

Question 14

What is the major issue underlying high-stakes testing?
A)A decreased emphasis on standardized testing in favor of authentic testing
B)An increased dependence on standardized tests for decision making
C)The relatively high expense of testing large numbers of students
D)The lack of validity of many standardized tests in use today

Accepted Answer

High-stakes testing refers to the practice of using test scores to make significant decisions about students, teachers, schools, and districts. The major issue underlying high-stakes testing is the increased dependence on standardized tests for decision making, which can have negative consequences for all stakeholders involved.

Question 15

Jennifer,a seventh grader,received a percentile rank of 90 on a standardized vocabulary test.This percentile rank indicates that she
A)exceeded the eighth-grade performance level.
B)is as advanced as a ninth grader.
C)scored above the average for seventh graders.
D)should be assigned a grade of A for her performance.

Accepted Answer

A percentile rank of 90 indicates that Jennifer scored better than 90% of the students who took the same standardized vocabulary test, which means she scored above the average for seventh graders.

Question 16

The type of standard score that represents the broadest range of raw scores is the ________ score.

Accepted Answer

The answer of The type of standard score that represents...

Question 17

A)higher.
B)lower.
C)similar.
D)unpredictable.

Accepted Answer

Including regular and advanced students would likely lower Martin's percentile rank, as the overall performance level of the group would increase.
