Study Notes
Levels of Measurement
- Four different scales of measurement exist for defining data: nominal, ordinal, interval, and ratio.
- Nominal Scales: Characterised by named variables only. No inherent order or numerical value.
- Ordinal Scales: Involve named variables ordered in a specific sequence. The intervals between the ordered values are not necessarily equal.
- Interval Scales: Involve named variables ordered in a specific sequence with equal intervals between values. No true zero point.
- Ratio Scales: Include named variables ordered with equal intervals and a true zero point. Ratios between values are meaningful.
Scale Relationships
- A nominal scale is the simplest type.
- An ordinal scale includes the characteristics of a nominal scale plus the ordering of variables.
- An interval scale includes the characteristics of an ordinal scale plus equal intervals between values.
- A ratio scale includes the characteristics of an interval scale plus a true zero point.
