Question

A medical doctor diagnosed a patient of jaundice and recorded the following variables:

(i) Temperature, (ii) Patient number, (iii) Weight.
What will be the respective scales on which the variables will be measured?

Answer 1

The variables are:

Temperature: The variables for this can be Celcius degrees or Farenheit degrees, depending on where the medical doctor is from.

Patient number: this can be any integer number, as the patient is received in the hospital they assign him a number.

Weight: We commonly hear that the unit for weight is "grams", while the actual unit is called is "gram force", because gram is a unit of mass, and weight is actually a force, so here the correct unit is "gram force" or "kilogram force" (that are equivalent)
