Statistic - (answers)a numerical measure that describes an aspect of a sample.



Nominal Level - (answers)The nominal level of measurement applies to data that
consists of names, labels, or categories. There are no implied criteria by which the
data can be ordered from smallest to largest. We can put the data into categories.



Ordinal Level - (answers)The ordinal level of measurement applies to data that
can be arranged in order. However, differences between data values either
cannot be determined or are meaningless. We can order the data from smallest
to largest or "worst" to "best". Each data value can be compared with another
data value.



Interval Level - (answers)The interval level of measurement applies to data that
can be arranged in order. In addition, differences between data values are
meaningful. We can order the data and also take the differences between data
values. At this level, it makes sense to compare the differences between data
values. For instance, we can say that one data value is 5 more than or 12 less than
another data value.



Ratio Level - (answers)The ratio level of measurement applies to data that can be
arranged in order. In addition, both differences between data values and ratios of
data values are meaningful. Data at the ratio level have a true zero. We can order
the data, take differences, and also find the ratio between data values. For
instance, it makes sense to sat that one data value is twice as large as another.
