Answer 1

Answer:

Ratio (There is a chance of getting 0 / 10 correct!)

Explanation:

Ratio scale of measurement: In statistics or research methods, the ratio scale of measurement is defined as one of the different types of variable measurement scale which are considered as a quantitative technique. It allows the experimenter or the researcher to compare distinct intervals and differences.

It is considered as the fourth-level in variable measurement and encompasses a zero character or point of origin and therefore considered as an important feature in the ratio scale.
