QUESTIONS FROM assessment and statistics QUIZZES
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
4
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.
at the end of a unit on world war II, students take a test on the major aspects of the war.
the teacher uses the test results for grading and evaluation. this is an example of what
type of assessment? *** Summative
What assessment provides feedback to a teacher after student practice and is usually
not used for grading purposes? *** Formative
What assessment helps teachers understand student's skills and prior knowledge in
order to adjust future lessons? *** Diagnostic
What assessments usually involve an activity or application of hands on skills? ***
Performance
A 2 grade student throws violent tantrums in class. The teacher has tried several known
classroom management techniques, but the tantrums are becoming more severe.
Which response would best help this student? *** Ask for help from other school or
district professionals
not- tell parents its getting worse
Why? The severity of the situation indicates that expertise from other professionals is
needed. Other choices have most likely been addresses and are too passive for severe
and violent behavior.
A teacher is writing an assessment to test students' knowledge of mass, volume, and
density. Which one of the following BEST describes the types of problems the teacher
should include in the exam?
A. Ask students to generalize learned concepts to new scenarios
C. Question students on definitions of mass, volume, and density. *** A., assessments
should be used to determine whether students can generalize concepts to new
scenarios and problems. Having students calculate the mass of an object in the room,
