With data, when zero means “nothing", these scores would be at the ____ level of measurement.
A
Nominal
B
Ordinal
C
Interval
D
Ratio
Explanation: 

Detailed explanation-1: -Unlike on an interval scale, a zero on a ratio scale means there is a total absence of the variable you are measuring.

Detailed explanation-2: -An interval scale lacks a true zero. Examples of scales without a true zero include rating scales, temperature, and measures of latitude and longitude.

Detailed explanation-3: -Just like the interval scale, the ratio scale is a quantitative level of measurement with equal intervals between each point. What sets the ratio scale apart is that it has a true zero. That is, a value of zero on a ratio scale means that the variable you’re measuring is absent.

Detailed explanation-4: -If you use the absolute scale, for which ‘absolute 0’ is the 0, then that’s a ratio scale. For example, 0o Kelvin is the same as −273.15o C.
