What Are The 4 Levels of Measurements?

Measurements play an important role to understand the exact records of variables and these measurements are divided into 4 levels, each ranked from low to high:

Nominal

It is the lowest rank in the measurements; in this, the data can only be categorized. Understanding the difference between independent and dependent variables is crucial at this level.

Ordinal

This level of measurement is one notch up from the nominal because here data is categorized along with rank. Effective essay planning can benefit from using ordinal data to structure arguments and evidence.

Interval

This measurement is more organized; here data can be spaced, categorized, and ranked. This organization is key in critical analysis of research papers.

Ratio

The highest level of the measurements; the data in this level can be divided into 4 imperative aspects, evenly spaced, ranked, and has a natural zero. Detailed research, such as dissertations, often relies on ratio measurements for precise data analysis.

Understanding these levels is essential for accurate data analysis and interpretation, as highlighted in the research onion framework.
