National Physical Therapy Assistants Examinations - Additional Info Sample Questions

The type of measurement scale where the intervals between adjacent values are equal and there is a true zero point is which of the following?

Correct Answer:
ratio
the correct answer to the question is "ratio."

a ratio scale is one of the four levels of measurement used in statistical analysis, and it represents the highest level of measurement. this type of scale possesses a clear definition of zero, and the intervals between the values are equidistant. in other words, not only is there a true zero point, but the difference between any two values is meaningful and consistent.

for example, consider measurements of weight. if an object weighs 0 grams, it truly has no weight, establishing a true zero point. if another object weighs 10 grams and a third weighs 20 grams, the difference between these weights (10 grams) is consistent. this is significant because it allows for the computation of ratios; for instance, the third object is twice as heavy as the second object.

unlike the ratio scale, the interval scale also has equal intervals between values but lacks a true zero point. for example, in temperature measurements in celsius or fahrenheit, the difference between 20 degrees and 30 degrees is the same as the difference between 30 degrees and 40 degrees. however, 0 degrees does not signify the absence of temperature—it is simply a point on the scale. therefore, you cannot say that 20 degrees is twice as hot as 10 degrees, which is a calculation that a ratio scale would support.

the other two scales are ordinal and nominal. the ordinal scale ranks data while maintaining the order between items but does not ensure equal intervals between ranks. for example, finishing positions in a race (first, second, third) indicate order but do not quantify the difference in time or performance between positions. the nominal scale categorizes data without any order or interval, such as categorizing individuals by their favorite color or by their nationality.

in conclusion, the ratio scale is unique in its ability to express the magnitude of measurements, provide equidistant intervals, and include a true zero point, allowing for meaningful comparisons and mathematical operations such as multiplication and division, which are not possible with ordinal, nominal, or interval scales.
