It is reasonable to state that one object has twice as much of the attribute property when it has a score of 60 and the other object has a score of 30 when measurement is on a(n) scale.

The correct answer is:

Ratio Scale

Explanation:

A ration scale of measurement is one that has equal units of measurement, and has an absolute value of zero. Measurements below the zero point on the scale is not possible. for example in the measurement of height in meters, the lowest measurement possible is 0 meter, a measurement of - 1 meter will make no mathematical sense. In this example, if a score of 60 is said to have twice as much attributes than a score of 30, it means that this attributes are measured from a reference zero point, because truly, 60 is twice as much as 30, from a zero point on a scale.

The other scales of measurements include;

nominal scale of measurement; which contains mainly categorical data and is mainly used in form of tags rather than showing magnitude or intervals. Example is grouping a group of adults into married, divorced or single.

Ordinal scale; this scale shows hierarchical series or ordered series, but does not show intervals between the elements. example is in classifying the positions of participants in a race as first, second or third etc. There is an ordering, as the first position is on top of the list, but it will now make sense to say the distance between the attribute of first to third position is the same as the distance between the attributes between third and fifth position, as there is no scale.

Interval scale; this scale of measurement does not have a limit zero value which represents the least possible point on a scale, but the intervals between different units on the scale can be compared logically. Example is the measurement of temperature using the Fahrenheit scale, where the temperature can go as low as - 20°F, below the zero point, and a distance of 3°F to 5°F can be said to be equal to a distance of 10°F to 12°F.
