FEEDBACK LOG AND SCORE JENNIFER
HOFFMAN PRACTICE REVIEWED QUESTIONS
2026 VERIFIED ANSWER KEY
◉ A student conducting a research study was told by her professor
to use a scatterplot in conjunction with calculating the correlation
coefficient. She discovered that the data points clustered along a
straight line; this means that: Answer: a linear relationship exists
among the variables
◉ In a follow-up study, a researcher reported that the correlation is
.85. In the initial study, the correlation was .78. This means there is
a/an: Answer: stronger correlation between the variables in the
follow-up study
◉ 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? Answer: 10
◉ The variance is determined to be 36. What would be the standard
deviation? Answer: 6
,◉ A researcher determines that there is a positive correlation
between sleep and test scores; this means that as the amount of
sleep is increased, then test scores will: Answer: increase
◉ In studying the correlation between the number of hours studied
and scores on the comprehensive exam, the researcher found a
correlation of .30. According to Cohen's guidelines, what would this
mean regarding the strength of the relationship? Answer: medium
◉ The teacher grades the papers and determines the following set of
scores: 90, 85, 87, 85, 92, 90, 83, 85, and 98. What is the mode?
Answer: 85
◉ A T score has a fixed mean of __________ and a fixed standard
deviation of __________. Answer: 50; 10
◉ A type of standard score with a mean of 100 and a standard
deviation of 15 is: Answer: Deviation IQ
◉ Grade equivalents are useful because they: Answer: Can easily
provide a basis of comparison of a student's performance with other
students at a given grade level.
, ◉ Which type of normalized standard score is widely used in
education and categorizes test performance in nine broad units?
Answer: Stanines
◉ Z scores, T scores, and deviation IQs are examples of: Answer:
standard scores
◉ Aptitude, intelligence, and achievement tests are all examples of:
Answer: maximum-performance tests
◉ Denise took an aptitude test that was first taken by a large group
of male engineers, on whom the test was standardized. Denise is a
nurse. What might be a concern when interpreting her test scores?
Answer: the norm group is not relevant
◉ In a test which results in a report that describes how well the test
taker does in comparison with other individuals, it is important to
consider whether the: Answer: norm group is clearly defined
◉ A raw score can be transformed into any type of standard score by
first: Answer: converting the raw score to a Z score
◉ A researcher is concerned with measuring internal consistency
reliability and has decided to use the Kuder-Richardson Formulas
