Statistical Assessment -National
Counselor Exam Practice
When comparing the four scales of measurement, what distinguishes the interval scale
from the ratio scale? - ANS-Absolute zero
A research team designed a demographic questionnaire to collect information about
participants. Which of the following variables identified on the questionnaire provides an
example of an ordinal scale variable? - ANS-Rank in the military
When looking at a list of student's test scores, the teacher notices that one test score is
extremely lower than the majority of the scores. This is known as a(an): - ANS-outlier
A teacher analyzes the scores from a recent test and determines a positively skewed
curve. She infers that the majority of students knew: - ANS-only a few of the answers
due to low scores
A researcher is looking for a specific study report, in which he knows the kurtosis value.
He reads the following kurtosis value in various reports. Which one supports a
mesokurtic distribution? - ANS-0
There are 12 participants who agree to take the test for a study focused on wellness.
The total of all the participants' scores is 96. What is the mean? - ANS-8
The teacher has a small class with only 7 students. The teacher grades their homework
and reports scores of 10, 7, 8, 12, 9, 11, and 13. What is the median? - ANS-10
Grade equivalents are useful because they - ANS-can easily provide a basis of
comparison of a student's performance with other students at a given grade level.
A school interested in measuring students' progress in academic subjects throughout
the school years might choose to use - ANS-growth scale values (GSV).
In order to convert a raw score to a Z score, the following values are needed: - ANS-the
raw score of the test taker, (2) the mean of the raw scores, and (3) the standard
deviation of the raw scores.
If the reliability coefficient of a test is determined to be .27, what percentage is attributed
to random chance or error? - ANS-73%
, The test manual reports a reliability coefficient (r) of .92, which means: - ANS-92% of
the variance in scores is explained by real differences
The researcher determines that the reliability coefficient is .65. This means the reliability
is: - ANS-not generally acceptable
The researcher reports the standard error of measurement (SEM). This is: - ANS-the
spread of scores of a single individual if he/she took a test repeated times
Jose has developed a test that has poor reliability. He can seek to increase reliability by:
- ANS-increasing the number of test questions
Keisha receives a 79 on the test. This is her:
Group of answer choices true score reported score observed score predicted score -
ANS-observed score
When the researcher interprets the reliability coefficient, the closer the score is to 0: -
ANS-the more the scores represent random error
Validity coefficients greater than _________ are considered in the very high range. -
ANS-.50
Criterion-referenced tests refer to instruments that: - ANS-Compare scores to a pre-
established standard
Norm-referenced tests refer to instruments that: - ANS-Compare scores to a norm
group
The teacher grades the papers and determines the following set of scores: 90, 85, 87,
85, 92, 90, 83, 85, 98. What is the mean? - ANS-85
The teacher calculates the highest score as being 97 and the lowest score as being 75.
What is the range? - ANS-22
The variance is determined to be 36. What would be the standard deviation? - ANS-6
A teacher reports that the class scores are generally distributed according to a bell
curve. This means: - ANS-100% of the scores fall between -3 and +3 standard
deviations from the mean
A researcher determines that there is a positive correlation between sleep and test
scores. This means as the amount of sleep is increased then test scores: - ANS-
increase
A teacher determines that the correlation between eating breakfast and doing well on
the test is zero. This means: - ANS-there is an absence of a correlation
