ABCTE PTK ASSESSMENT PRACTICE QUESTIONS
WITH 100% VERIFIED AND CORRECT ANSWERS
An 11th grade class has just finished reading the grapes of wrath. What is the best way to assess
students understanding of the book ? - a homework assignment that requires students to reflect on
facts and key points
why? the assessment is aligned with lesson content. the question does not state that the teacher has
taught the class about literary terms, such plot and theme like choice c addressed (written test
about plot, theme, and main characters)
What is the unbiased standard deviation of the following sample?
Student Score 1 3 5 7 9 - 4.28
The correct answer is B.
Step 1: The mean is 5.
Step 2: Subtracting the mean from each score.
(1−5) = −4
(3−5) = −2
(5−5) = 0
(7−5) = 2
(9−5) = 4
Step 3: Squaring the result for each score.
16
4
, 0

16
Step 4: Adding the results (16 + 4 +0 + 4 + 16) = 40
Step 5: Dividing 40 by the number of scores minus 1 = 10
Step 6: The square root of 10 is approximately 3.16.
Which of the following BEST describes what a Pearson coefficient of zero between scores on two
tests would indicate to a teacher? - The scores on the two tests are ...unrelated
A Pearson coefficient of zero indicates that the scores on the two tests are not related in a reliable
or predictable way.
If the graph of a data distribution shows that the mean is graphed to the right of the mode, which of
the following is most likely true? - positively skewed
The correct answer is A. In a positively skewed frequency distribution, the mean moves to the right
of the mode and the majority of the scores fall below the mean. For a frequency distribution that is
negatively skewed, the mean moves to the left of the mode and is shaped so that the majority of its
scores fall above its mean. In a positively skewed distribution, the median is generally less than the
mean.
Which of the following BEST describes a graph of a bimodal distribution? - There are two points of
high frequency data within the distribution.
The correct answer is B. "Bimodal" means that there are two modes or peaks within the same
distribution of data. The two modes will not necessary reflect two extremes and may be clustered
near one another.
