Study Notes
Levels of Measurement
- Four levels of measurement: nominal, ordinal, interval, and ratio.
Nominal Measurement
- Classifies data using numbers, words, letters, or symbols without any order.
- Example: Gender classification as Female (F), Male (M), and Transgender (T) represents nominal measurement.
Ordinal Measurement
- Represents ordered relationships among observations while still classifying data.
- Example: Student rankings based on grades; highest score (100) is ranked first, second score (92) is ranked second, and so on, indicating an order.
Interval Measurement
- Classifies, orders, and indicates equal distances between scale points.
- Example: Measurement of anxiety scores where the difference between scores of 10 and 11 is the same as between 40 and 41; temperature in Celsius illustrates equal intervals (e.g., the difference between 94°C and 96°C is the same as that between 100°C and 102°C).
Ratio Measurement
- Similar to interval measurement but includes a true zero point, making it possible to express ratios.
- Example: Height or weight measurements can have a value of zero; equal distances exist between measurement points, and comparisons can be made (e.g., one object can be twice as heavy as another).
