Which scale is the simplest form of measurement ? Correct Answer Nominal

Scale:

A scale is basically a continuous spectrum or series of categories and has been defined as any series of items that are arranged progressively according to value or magnitude, into which an item can be placed according to its quantification.

Key Points

Four popular scales in research are:

Nominal Scale:

  • It is the simplest form of measurement i.e. it helps in just identifying.
  • Categorical data are measured on nominal scales which merely assign labels to distinguish categories.
  • For eg. Catholic = 1, Jewish = 2, Muslim = 3 and Other = 4 and Male = 1, Female = 2.
  • Here people are just categorised but no hierarchy is given.

Ordinal Scale:

  • It is a scale that arranges objects or alternatives according to their magnitude.
  • For eg.
  • Merit = A Grade, B Grade, C Grade, etc.
  • Ranking of players in cricket = Rank 1, Rank 2, etc.
  • The difference between the categories is hard to quantify.

Interval Scale:

  • It is a scale that not only arranges objects or alternatives according to their respective magnitudes but also distinguishes this ordered arrangements in units of equal interval.
  • Absolute zero point is not present in this scale.
  • For eg. Temperature scale in Fahrenheit.

Ratio Scale:

  • A ratio scale is a scale that possesses absolute rather than relative qualities.
  • It has an Absolute zero point.
  • For eg. Money, Weight, Temperature in Kelvin.

Hence, it could be concluded that nominal scale is the simplest form of measurement.

Assertion A): U-shaped long-run average cost curve is based on the assumption that economies of scale prevails at small levels of production and diseconomies of scale prevails at larger level of production. Reason R): Decreasing returns to scale arises primarily because as the scale of operation increases, it becomes even more difficult to manage the firm effectively.
