Question

For each of the variables listed below, indicate whether the measure is nominal, ordinal, interval, or ratio:

a. Degrees, on the Celsius scale

b. Student’s class rank

c. Number of cancerous lymph nodes detected in a patient

d. Respiratory rate

e. Religious preference

f. Military rank

g. Type of delivery (vaginal vs cesarean)

h. IQ test score

a. Degrees, on the Celsius scale : Since there is a scale involved which has both maximum and minimum values, this is an interval variable.

b. Student’s class rank : Since there is a hierarchy, this is an ordinal variable.

c. Number of cancerous lymph nodes detected in a patient : Since this is a mere number, this is a nominal variable.

d. Respiratory rate : Since this can take any value and has a zero, this is a ratio variable.

e. Religious preference : Since this can be one value out of a given set with no order, this is a nominal variable.

f. Military rank : Since there is a hierarchy, this is an ordinal variable.

g. Type of delivery (vaginal vs cesarean) : Since there are fixed number of values without an order, this is a nominal variable.

h. IQ test score : Since there is a zero and no maximum score, this is a ratio variable.
