Measurement scales
I. Nominal scale names or classifies only (social security number, baseball, football uniform examples).
II. Ordinal scale also ranks beside naming (height, baseball standings, beauty pageant examples). Most psychological tests are only ordinal scales.
III. Interval scale, beside previous qualities, also has equal intervals and an arbitrary zero (centigrade/Celsius thermometer example).
IV. Ratio scale (Q student, handout) also has a true/absolute zero, which allows comparisons in terms of ratios (Kelvin thermometer, height/weight exams). Math uses ratio scale.
