67. A researcher wants to know what the average variation is in altimeters of small, privately
owned airplanes. The task of determining this is expensive and time-consuming, if even
possible, given the large number of such airplanes. The researcher decides to use government
records to randomly locate the owners of ten such planes and then get permission to test the
altimeters. When the researcher is done the data gathered from the group of ten will be used to
reach conclusions about all small, privately owned airplanes. This process can best be
described as ___.
a) data statistics
b) research statistics
c) descriptive statistics
d) inferential statistics
e) nonparametric statistics
Answer: d
Difficulty: Medium
Learning Objective: Define important statistical terms, including population, sample, and
parameter, as they relate to descriptive and inferential statistics.
