Study Notes
Scales of Measurement
- There are four primary scales of measurement: nominal, ordinal, interval, and ratio
- These scales have different properties that distinguish them from one another
Nominal Scale
- Only has the assignment property
- Used to categorize or label objects
- Examples: gender, occupation, country of origin
Ordinal Scale
- Has assignment and order properties
- Used to rank objects in a specific order
- Examples: ranking preferences, educational level, income level
Interval Scale
- Has assignment, order, and distance properties
- Used to measure attitudes, opinions, and index numbers
- Examples: temperature, IQ scores
- Statistical techniques that can be used: range, mean, standard deviation, product-moment correlation, t-tests, ANOVA, regression, and factor analysis
Ratio Scale
- Has all four properties: assignment, order, distance, and origin
- Enables the researcher to identify or classify objects, rank objects, and compare intervals or differences
- Examples: weight, height, age, sales, cost, customer numbers
- All statistical techniques can be applied, including specialized statistics such as geometric mean, harmonic mean, and coefficient of variation
Likert Scale
- Focuses on the degree of agreement or disagreement
- Assigning numbers helps in accurate understanding of a phenomenon, facilitates easy communication, and provides objectivity
- Used in marketing research to measure variables such as attitudes, opinions, and index numbers
Understanding the characteristics of interval scales, including arbitrary origin and units, and statistical techniques for data analysis.
