Scale
Scale is a classification that describes the nature of information within the values assigned to variables.
Types of scales:
1. Nominal scales
Nominal scales contain the least amount of information. In nominal scales, the numbers assigned to each variable or observation are only used to classify the variable or observation.
2. Ordinal scales
Ordinal scales present more information than nominal scales and are, therefore, a higher level of measurement. In ordinal scales, there is an ordered relationship between the variable’s observations.
3. Interval scales
Interval scales present more information than ordinal scales in that they provide assurance that the differences between values are equal. In other words, interval scales are ordinal scales but with equivalent scale values from low to high intervals.
4. Ratio scales
Ratio scales are the most informative scales. Ratio scales provide rankings, assure equal differences between scale values, and have a true zero point.
