Flashcards

Nominal Scale

Data is simply categorized into groups with no order or numerical value. Think of it as names or labels.

Ordinal Scale

Data is categorized into groups with a clear order, but the intervals between the groups may not be equal. Think of it as ranking preferences.

Interval Scale

Data is categorized into groups with a clear order and equal intervals between groups. Think of it as measuring temperature.

Ratio Scale

Data is categorized into groups with a clear order, equal intervals, and a meaningful zero point. Think of it as measuring weight.

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.
