Measurement and Scaling: Fundamentals and Comparative Scaling

16 important questions on Measurement and Scaling: Fundamentals and Comparative Scaling

How do you call the assignment of numbers or other symbols to characteristics of objects according to specific pre-specified rules?

Measurement

How do you call the generation of a continuum upon which measured objects are located?

Scaling

How do you call the unique labels or descriptors that are used to designate each value of the scale; all scales possess description?

How do you call the relative sizes or positions of the descriptors on a scale?

Order

How do you call characteristics of scales that absolute differences between the scale descriptors are known and may be expressed in units?

Distance

How do you call the characteristic of scales indicating that the scale has a unique or fixed beginning or true zero points?

Origin

How do you call a scale whose numbers serve only as labels or tags for identifying and classifying objects with a strict one-to-one correspondence between the numbers and the objects?

Nominal scale

How do you call a ranking scale in which numbers are assigned to objects to indicate the relative extent to which some characteristic is possessed?

Ordinal scale

How do you call a scale in which the numbers are used to rate objects such that numerically equal distances on the scale represent equal distances in the characteristic being measured?

Interval scale

How do you call the highest-level scale, which allows the researcher to identify or classify objects, rank-order the objects, and compare intervals or differences?

Ratio scale

How do you call a comparative scaling technique in which a respondent is presented with two objects at a time and asked to select one object in the pair according to some criterion?

Paired comparison scaling

How do you call an assumption mad to convert paired comparison data to rank-order data, which assumes that if brand a is preferred to brand b and brand b is preferred to brand c, then brand a is preferred to brand c?

Transitivity of preference

How do you call a comparative scaling technique in which respondents are required to allocate a constant sum of units such as points, dollars, chits, stickers, or chips among a set of stimulus objects with respect to some criterion?

Constant sum calling

How do you call a comparative scaling technique that uses a rank order procedure to sort objects based on similarity with respect to some criterion?

Q-sort scaling

What are the four primary types of scales?

  • Figurative: nominal scale
  • Ordinal scale
  • Unconstrained zero point: interval scale

What are the six different comparative and noncomparative scales?

  • Semantic differential scale
  • Constant sum, Q-sort scales
  • Arranged in order: rank order scale
  • Likert scale
  • Engaged: paired comparison scale
  • Stapel scale
