61.Sally steps on her bathroom scale, and it tells her that she weighs 145 pounds. When she steps on it again after her shower, she gets the same result. In fact, it has told her that her weight is stable at 145 pounds for several days now. This is very distressing to Sally, because she actually only weighs around 127 pounds. Which of the following could be said about Sally’s scale?
a.
It is unreliable.
c.
It lacks standardization.
b.
It is invalid.
d.
It has not been properly normed.
62.When a measure being used in a research study actually assesses what the research thinks it measures, it would be described as being
a.
reliable.
c.
standardized.
b.
valid.
d.
experimental.
63.When a measure being used in a research study produces a consistent index of a characteristic, it would be described as being
a.
reliable.
c.
standardized.
b.
valid.
d.
experimental.
64.Validity is to reliability as
a.
study is to experiment.
c.
positive is to negative.
b.
cause is to correlation.
d.
accuracy is to consistency.
65.Marcella is interested in studying the physical development of girls between 7 and 10 years of age. It is impractical to think that she could study every such girl in the country, so instead she selects a smaller group of girls in this age range to study. The group that Marcella studies is a(n) ________, and the larger group that they represent is a(n) ________.
a.
population; sample
c.
in-group; out-group
b.
out-group; in-group
d.
sample; population
66.Why is it necessary to study a sample of individuals that is representative of a larger population?
a.
because a sample gives better statistical strength than a population, and this allows a research to “confirm” any hypothesis (s)he has made
b.
because there are ethical restrictions against gathering data from a population, but not a sample.
c.
because a population will include too many people who would be unwilling to answer questions honestly.
d.
because it would be impractical, perhaps even impossible, to attempt to gather data from an entire population of individuals.
67.Which of the following are the two general designs that can be used to conduct research?
a.
experimental studies and quasi-experimental studies
b.
observational studies and self-report studies
c.

d.
correlational studies and experimental studies
68.Suzy wants to study whether there is a relationship between the phases of the moon and the tides that occur in the ocean. She does so by making nightly observations of the moon and recording its phases, and by measuring the tides of the ocean at regular intervals every day and night. The type of research that Suzy is conducting—examining relationships as they naturally exist in the world—is called
a.
quasi-experimental research.
c.
correlational research.
b.
experimental research.
d.
analogue research.
69.In a correlational study, variables are always studied
a.
as they exist naturally.
c.
during an experiment.
b.
after some manipulation.
d.
at the population level.
70.The statistic that is used to depict the relationship between to variables that has been uncovered in a correlational study is called the correlational ________.
a.
multiplicand
c.
permutation
b.
deviation
d.
coefficient
0
