136) A

would be a/an:
A) case study.
B) correlational study.
C) survey.
D) naturalistic observation.

138) Professor
Holden gives a psychology exam on the origins of intelligence. She gives a
short answer question based on the IQ scores of a parent–child pair. In order
to answer the question correctly, her students need to remember that:
A) given these variables, the
correlation will be positive.
B) to say that a relationship exists,
you need more than one pair of values to compare.
C) given these variables, the
correlation will be uncorrelated.
D) given these variables, the
correlation will be negative.
139) Dr.
Myers found that students in her class who scored 80% or better on the mid-term
exam were likely to score 70% or better on the final exam. Students who scored
below 60% on the midterm, however, were likely to end up failing the final
exam. These test results suggest:
A) there is a strong negative
correlation between the midterm and final exam scores.
B) students who do poorly on the
midterm exam give up and fail to study adequately for the final exam.
C) the midterm and final exam scores
are not correlated.
D) there is a strong positive
correlation between the midterm and final exam scores.
140) Imagine
that the personality traits of conservatism and aggression have a strong
negative correlation. If Sue has a score on aggression that is very low:
A) it is impossible to predict her score
on the conservatism scale without more information.
B) she will likely have an average
conservatism score.
C) she will likely have a high score on
conservatism.
D) she will likely have a low score on
conservatism.
