Question

determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. serial numbers on cars. choose the correct answer below. a. 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 point. b. the interval 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 no natural starting point. c. the nominal level of measurement is most appropriate because the data cannot be ordered. d. the ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.

Explanation:

Serial numbers on cars are just labels. They cannot be ordered in a meaningful numerical - order sense (e.g., a serial number of 100 is not "greater" or "less" than a serial number of 200 in a way that represents a quantity). They are used for identification purposes only. The nominal level of measurement is for data that can't be ordered.

Answer:

C. The nominal level of measurement is most appropriate because the data cannot be ordered.
