Which uses the higher level of measurement: temperature in Fahrenheit degrees or weight in kilograms?
a. Both are measured at the same level
b. Not enough information given to make a decision
c. Temperature
d. Weight
ANS: D
Interval-scale measurement is distinguished from ratio level in that there is no zero point on the interval scale. A temperature of zero does not indicate the absence of temperature. Changes in temperature, however, have equal numerical distance between the intervals of the temperature scale, and the temperature value is expressed as a continuum. These properties indicate that temperature is an interval level of measurement. Weight in kilograms does have an absolute zero point. A person can have no weight; therefore weight is expressed as a ratio level of measurement, the highest level.
Since weight has an absolute zero and temperature does not, they are not the same level of measurement.
There is enough information to make this decision.
Temperature in Fahrenheit degrees does not have an absolute zero therefore this measure is an interval measure.
