Question 1

The definition of a norm-referenced test as compared to a criterion-referenced test differs primarily with respect to

Accepted Answer

Norm-referenced tests compare individuals' scores to the scores of a representative sample of test takers, while criterion-referenced tests compare individuals' scores to a predetermined standard or criterion. Therefore, the score to which test takers are compared differentiates the two types of tests.

Question 2

The concept of mental age as a means of describing performance on an intelligence test has been

Accepted Answer

The answer of The concept of mental age as a...

Question 3

Deciles divide a distribution into ________ equal parts.

Accepted Answer

Deciles divide a distribution into 10 equal parts.

Question 4

Sampling all different subgroups within a population is an example of

Accepted Answer

Stratified sampling involves dividing the population into subgroups or strata and then randomly selecting samples from each subgroup. This ensures representation from all subgroups within the population, making it the best choice for sampling all different subgroups. Random sampling only selects samples randomly without considering subgroups, incidental sampling relies on convenience and may not represent all subgroups equally, and purposive sampling involves selecting samples based on specific criteria, which may not include all subgroups within the population.

Question 5

If the calculated value of the correlation coefficient for two variables is 0,what would the resulting scatterplot look like?

Accepted Answer

The scatterplot would have no clear pattern or relationship between the two variables. A correlation coefficient of 0 indicates no linear relationship between the variables. However, there could be a non-linear relationship or a relationship between the variables that is not captured by the correlation coefficient. Therefore, we cannot infer anything about the scatterplot from the correlation coefficient alone.

Question 6

An investigator researching behavior of corporate presidents employs college students enrolled in Introductory Psychology as research subjects.These students are BEST referred to as

Accepted Answer

The students enrolled in Introductory Psychology class are not chosen based on any specific criteria, but rather because they are available and willing to participate in the study. This makes them an incidental sample, which is a non-probability sampling method where the selection of participants is based on convenience or availability.

Question 7

The type of sample that is convenient or available for use is referred to as

Accepted Answer

An incidental sample is a type of non-probability sampling technique where the sample is chosen by convenience or based on what is easily available. This method is often used in situations where it's difficult or expensive to gather a more representative sample.

Question 8

Which of the following is TRUE of a population in the statistical sense?

Accepted Answer

A population in statistics refers to the entire group of individuals or instances about whom we are interested. It can be as small as any finite number of individuals, including as few as two, such as in the case of two home-bound students.

Question 9

Subgroup norms can best be described as a normative sample

Accepted Answer

Subgroup norms by definition refer to a normative sample that has been segmented in some way, such as by age, gender, ethnicity, or clinical population. This allows for more targeted comparisons and interpretations of test scores within specific subgroups.

Question 10

National anchor norms provide

Accepted Answer

National anchor norms provide an indication of the equivalency of scores on various tests that are administered nationally. They help establish a common scale for comparing scores from different tests and measuring growth over time. They are commonly used in education and other fields where standardized testing is used.

Question 11

Reference to a "standard drink" in the psychology literature conveys information to knowledgeable readers about

Accepted Answer

A "standard drink" refers to a specific amount of alcohol that is present in a particular beverage. This information is useful for understanding the amount of alcohol an individual is consuming, as well as for making informed decisions about safe drinking practices. The other options are either overly specific or unrelated to the concept of a standard drink.

Question 12

Which of the following is TRUE of a sample in the statistical sense?

Accepted Answer

A sample is a subset of a population, so it cannot have more members than the population itself.

Question 13

The terms percentile and percentage correct

Accepted Answer

Percentile and percentage correct are not synonymous, do not share the characteristic of not being a converted raw score, and their calculation does not both entail multiplying by 100 and dividing by the number of items. Percentile refers to the position within a distribution, while percentage correct is a straightforward calculation of correct items over total items, expressed as a percentage.

Question 14

A test is considered standardized if the manual for the test includes

Accepted Answer

A standardized test must have clearly specified procedures for administration, scoring, and normative data. Without any of these components, the test cannot be standardized, so all three options must be included in the test manual. Therefore, the correct answer is D.

Question 15

This tool is used to estimate or infer how far an observed score deviates from a true score,and it called

Accepted Answer

The tool being described is the standard error of measurement, which estimates the amount of error present in a test score. It is commonly used in educational and psychological testing to help interpret and evaluate test scores. Options A, B, and C are all measures of variability or central tendency, and do not relate specifically to the estimation of error in test scores.

Question 16

The statistic known as the standard error of measurement is BEST associated with which of the following?

Accepted Answer

The standard error of measurement is a statistical measure of the amount of error associated with a particular test or measurement. It is primarily used to assess the reliability of a test, as it provides an estimate of how much the scores on a test may vary due to measurement error.

Question 17

A test is said to be standardized if the test's manual contains clearly specified procedures for test

Accepted Answer

A standardized test not only specifies procedures for test administration, but also for scoring and interpretation. This ensures consistency across administrations and allows for meaningful comparison of test results.

Question 18

Traditionally,the term test standardization has been used interchangeably with the term

Accepted Answer

Test standardization refers to the process of ensuring consistency and uniformity in test administration and scoring, which is different from normalization, utilization, or calibration.

Question 19

A distribution of raw scores from a test administration is normally distributed.The test user wishes to summarize these data using percentiles.A potential problem here is that score differences in the middle area of the distribution

Accepted Answer

In a normally distributed set of scores, differences in the middle of the distribution (around the mean) are smaller in terms of raw scores compared to the tails. When these differences are converted into percentiles, the relative difference between scores can appear larger than it actually is, leading to an exaggeration of differences among scores that are close together in the middle of the distribution.

Question 20

If a standardized test is designed for hand-scoring by the test's user,then the test's manual will ideally contain an ample number of

Accepted Answer

The test manual will ideally contain both examples of correct and incorrect responses and examples of partially correct responses as these will help the test's user to hand-score the test accurately and consistently. Examples of correct and incorrect responses will help to establish clear criteria for marking, and examples of partially correct responses will help to guide the user in determining how many marks to assign for responses that are not entirely correct but show some understanding of the question or task. Having an ample number of all types of examples will ensure that the scoring is reliable and valid. Choice A and B alone do not cover all the necessary information needed in the test manual for hand-scoring. Choice D is incorrect as the test manual should contain examples for a standardized test designed for hand-scoring.
