Determine which of the four levels of measurement (nominal, ordinal,
interval, ratio) is most appropriate.
Miles of road - CorreCt Answers -The ratio level of measurement is most
appropriate because the data can be ordered, differences can be found and
are meaningful, and there is a natural starting zero point.
Determine which of the four levels of measurement (nominal, ordinal,
interval, ratio) is most appropriate.
Bushels of wheat - CorreCt Answers -The ratio level of measurement is
most appropriate because the data can be ordered, differences (obtained by
subtraction) can be found and are meaningful, and there is a natural
starting zero point.
In a survey, the responses of respondents are identified as 10 for a "yes", 20
for a "no", 30 for a "maybe", and 40 for anything else. The average (mean)
is calculated for 715 respondents and the result is 22.3.
Identify the level of measurement of the data.
Explain what is wrong with the given calculation. - CorreCt Answers -The
data are at the nominal level of measurement.
, Such data are not counts or measures of anything, so it makes no sense to
compute their average (mean).
In a set of data, blood lead levels are represented as 10 for low, 20 for
medium, and 30 for high. The average (mean) of the 529 blood lead levels is
25.4.
Identify the level of measurement of the data.
Explain what is wrong with the given calculation. - CorreCt Answers -The
data are at the ordinal level of measurement.
Such data should not be used for calculations such as an average.
Which of the following is associated with a parameter? - CorreCt Answers -
A parameter is a numerical measurement describing some characteristic of
a population. So, a parameter is associated with data that were obtained
from an entire population.
Which of the following consists of discrete data? - CorreCt Answers -The
number of suitcases on a plane is a number representing a count. This
would consist of discrete data.
Which level of measurement consists of categories only where data cannot
be arranged in an ordering scheme? - CorreCt Answers -The nominal level
of measurement is characterized by data that consist of names, labels, or
