Study Notes
Introduction to Scales in Questionnaires
- Measurement scales indicate how variables are recorded in quantitative analysis.
- Variables can have different values, such as height or test scores.
- Numbers in measurement scales must be assigned according to specified rules related to the variable's characteristics.
Nominal Scale
- The nominal scale is a classification system that assigns labels or numbers without implying any rank or order.
- Key characteristics include:
- Uniqueness: Each label or number identifies a distinct category.
- No inherent order: Values have no specific ranking or sequence.
- No numerical meaning: Assignments are names or identifiers with no quantitative implication.
- Equality/Inequality: Only allows for determining if two values belong to the same category or not.
Examples of Nominal Scale
- Flight Numbers: Used for identifying flight routes (e.g., Flight A = 1, Flight B = 2); numbers do not indicate value comparison.
- Categories in Research:
- Gender: Male (1), Female (2), Non-binary (3)
- Blood Type: A, B, AB, O
- Marital Status: Single, Married, Divorced, Widowed
- Postal Codes: Identifiers with no mathematical relevance.
Application of Nominal Scale
- Numbers can label variables such as smokers (1) and non-smokers (2); these labels lack mathematical significance.
- Labels should facilitate identification without allowing for mathematical operations.
Criteria for Labeling in Nominal Scale
- Categories must be exhaustive, ensuring that every element in the population or sample fits into one category with no exclusions.
