1. Data may be classified by one of the four levels of measurement. What is the name of the lowest level?
a. interval
b. nominal

d. ratio
e. simple

ANSWER: b
2. Identify the variable in the information below.
UV
The archeological site of Tara is more than 4000 years old. Tradition states that Tara was the seat
of the high kings of Ireland. Because of its
archeological importance, Tara has received extensive study (Reference: Tara:
An Archeological survey by Conor Newman, Royal Irish
Academy, Dublin). Suppose an archeologist wants to estimate the
IA
density of ferromagnetic artifacts in the Tara region. For this purpose, a random sample of 55 plots, each
of size 100 square meters, is used. The number of ferromagnetic artifacts for each plot is determined.
a. number of plots
b. size of the plots
?_
c. none of these choices
d. number of ferromagnetic artifacts per 100 square meters
e. density of ferromagnetic artifacts
M
ANSWER: d
3. Identify whether the variable in the information below is qualitative or quantitative.
GE
USA Today reported that 44.9% of those surveyed (1261 adults) ate in a fast-food restaurant from one to
three times each week.
a. qualitative
b. quantitative
EK
c. neither qualitative nor quantitative
d. qualitative as well as quantitative
e. Information does not have any variable.
