Question 1

Criterion-referenced assessment is valuable in determining mastery of basic skills.

Accepted Answer

Criterion-referenced assessment is a type of assessment that measures a student's performance against a set of predetermined criteria or standards. This type of assessment is useful in determining whether a student has achieved mastery of basic skills, as it measures their ability to meet specific learning objectives.

Question 2

Factors influencing whether a test is good or not include reliability, validity, and the absence of bias.

Accepted Answer

Reliability, validity, and the absence of bias are widely accepted as key factors in determining the quality of a test.

Question 3

A standard deviation is a measure of

Accepted Answer

Standard deviation is a measure of how much the scores vary from the average (mean) score. It represents the spread of scores around the mean.

Question 4

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?

Accepted Answer

Molly is involved in a high-stakes testing situation, as the results of the standardized test will determine her school placement. Criterion-referenced tests measure an individual's mastery of a specific set of skills or knowledge, but are not necessarily used for high-stakes decisions. Norm-referenced tests rank individuals in relation to others who have taken the same test, and are also not necessarily used for high-stakes decisions. Standardized aptitude tests assess an individual's potential to learn or perform in a certain area, but are not necessarily used for school placement decisions.

Question 5

Mr. Skiebert gave the same physics test to each of his three senior classes. Analysis of the data revealed the following descriptive statistics:  Compared to the two other classes, Mr. Skiebert can infer that students in Class One exhibit

Accepted Answer

Class One has the highest standard deviation, indicating greater variability in scores compared to the other two classes.

Question 6

When individual differences in achievement are to be reported, a norm-referenced grading system is appropriate.

Accepted Answer

Norm-referenced grading systems compare an individual's achievement to the achievement of the group (or "norm") they belong to, allowing for differentiation of performance and reporting of individual differences.

Question 7

In a normal distribution, which one of the following measures of central tendency will have the highest value?

Accepted Answer

The answer of In a normal distribution, which one of...

Question 8

Which of the following ranks the highest in terms of stanine scores?

Accepted Answer

Stanine scores range from 1 to 9, with 9 being the highest. A score of 8 is the highest among the given options.

Question 9

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?

Accepted Answer

The answer of IQ scores are normally distributed with a...

Question 10

Approximately what percentage of the scores in a normal distribution is higher than one standard deviation above the mean?

Accepted Answer

In a normal distribution, approximately 68% of the scores fall within one standard deviation above and below the mean (34% above and 34% below). Therefore, approximately 16% of the scores are higher than one standard deviation above the mean.

Question 11

A percentile rank score of 70 means that the student

Accepted Answer

Percentile rank score of 70 means the student scored as well as or better than 70% of all the test-takers. It does not necessarily indicate the number of correct answers, the grade level, or a majority of correct answers.

Question 12

Rob scored exactly in the middle of his class on the social studies exam. A valid interpretation of Rob's performance is that he scored exactly at the

Accepted Answer

The median is the middle value in a data set when it is ordered from least to greatest. Since Rob scored exactly in the middle, his score represents the median.

Question 13

Jennifer, a seventh grader, received a percentile rank of 90 on a standardized vocabulary test. This percentile rank indicates that she

Accepted Answer

A percentile rank of 90 means that Jennifer scored better than 90% of the students who took the test. This indicates that she performed above the average for seventh graders. It does not necessarily mean that she is as advanced as a ninth grader or that she should be assigned a grade of A for her performance, and there is no information given about exceeding the eighth-grade performance level.

Question 14

Norm-referenced tests are used to indicate progress toward specific competency levels.

Accepted Answer

Norm-referenced tests compare a student's performance to a norm group, rather than measuring progress toward specific competency levels, which is the purpose of criterion-referenced tests.

Question 15

Reliability is the degree to which a test measures what it is supposed to measure.

Accepted Answer

The answer of Reliability is the degree to which a...

Question 16

What is the median for the following set of scores? Scores: 66, 66, 74, 96, 98

Accepted Answer

To find the median, we need to order the scores from least to greatest: 66, 66, 74, 96, 98. The middle number is 74, which is the median.

Question 17

Measurement is the quantitative component of evaluation.

Accepted Answer

Measurement involves assigning numerical values to observed or assessed characteristics, behaviors, or traits in order to provide a basis for making judgments or comparisons. Evaluation, on the other hand, involves the systematic assessment of the worth or merit of an object or program. As such, measurement is a key component of evaluation as it provides the data needed to make judgments about the quality, effectiveness, or impact of an object or program.

Question 18

The Algebra I class mean and standard deviation are 80 and 10, respectively. The Biology II class mean and standard deviation are 79 and 4, respectively. Kristen scored 90 in Algebra I and 87 in Biology II. The most valid conclusion to be drawn from these data is that Kristen

Accepted Answer

The answer of The Algebra I class mean and standard...

Question 19

The relationship between the standard deviation and test scores is that the larger the standard deviation, the

Accepted Answer

The standard deviation is a measure of the spread or variability of scores in a distribution. Therefore, a larger standard deviation indicates that the scores are more spread out or variable, and a smaller standard deviation indicates that the scores are closer together or less variable. Therefore, the correct answer is A, "greater the variability in the distribution."

Question 20

Assessment is the term used to describe the process of gathering information about students' learning.

Accepted Answer

Assessment is indeed the process of gathering information about students' learning.
