Measurement Scales. Four different measurement scales have been identified that are used in quantitative research: (a) a nominal scale, (b) an ordinal scale, (c) an interval scale, and (d) a ratio scale (see Table 3.1). Researchers generally differenti-ate between numerals and numbers.
Ratio Scale can be defined as a quantitative scale that bears all the characteristics of an interval scale and a ‘true zero’ or ‘absolute zero’, which implies the complete absence of the attribute being measured.
3 sty 2020 · Ratio scale: A scale used to label variables that have a natural order, a quantifiable difference between values, and a “true zero” value. Some examples of variables that can be measured on a ratio scale include:
Ratio scales provide a wealth of possibilities when it comes to statistical analysis. These variables can be meaningfully added, subtracted, multiplied, divided (ratios).
Scales of measurement refer to ways in which variables/numbers are defined and categorized. Each scale of measurement has certain properties which in turn determines the appropriateness for use of certain statistical analyses. The four scales of measurement are nominal, ordinal, interval, and ratio.
