Answer to Question 1

ANS: B
Nominal-scale measurement is the lowest of the four measurement categories.
Interval data are considered the third highest level of measurement.
Ordinal data are considered the second highest level of measurement.
Ratio data are considered the highest level of measurement.

Nominal-scale measurement is used when data can be organized into categories. In this example, the researcher assigned data to ethnic categories.
Interval-scale data have equal numerical distances between each point.
Ordinal data are assigned into categories that can be ranked.
Ratio meets requirements of interval data and has a true zero.
