Question

for temperature and age can you classify each one to theor level of measurement such as nominal, ordinal, interval, or ratio and can you justify your classification

Answer 1

Ans:

Temperature :

Temperature in ⁰F and ⁰C is on interval scale.

A interval variable is a measurement where the difference between two values is meaningful. The difference between a temperature of 100 degrees and 90 degrees is the same difference as between 90 degrees and 80 degrees.

Temperature, expressed in F or C, is not a ratio variable. A temperature of 0.0 on either of those scales does not mean 'no heat'.

However, temperature in Kelvin is a ratio variable, as 0.0 Kelvin really does mean 'no heat'.

Age:

Age is continuous and ratio scale. A person's age have a meaningful zero point (birth).
