Psychologist Stanley Stevens developed the four common scales of measurement:
nominal, ordinal, interval and ratio
. Each scale of measurement has properties that determine how to properly analyse the data. The properties evaluated are identity, magnitude, equal intervals and a minimum value of zero.
What are scales of measurement in psychology?
In psychology and many disciplines that draw on psychology, data is classified as having one of four measurement scale types:
nominal, ordinal, interval, and ratio
. The measurement scale indicates the types of mathematical operations that can be performed on the data.

What are the 4 types of scales commonly used as levels of measurement in research?
In statistics, there are four data measurement scales:
nominal, ordinal, interval and ratio
. These are simply ways to sub-categorize different types of data (here’s an overview of statistical data types) .
What is scale and types of scale?
Introduction: There are 4 types of scales, based on the extent to which scale values have the arithmetic properties of true numbers. The arithmetic proper- ties are order, equal intervals, and a true zero point. From the least to the most mathematical, the scale types are
nominal, ordinal, interval, and ratio
.
What are the four scales of measurement APA?
any of four common methods for quantifying attributes of variables during the course of research, listed in order of increasing power and complexity:
nominal scale, ordinal scale, interval scale, and ratio scale
.
What is an example of interval?
An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include:
temperature (Farenheit)
, temperature (Celcius), pH, SAT score (200-800), credit score (300-850).
What scale of measurement is age?
Age, money, and weight are common
ratio scale variables
. For example, if you are 50 years old and your child is 25 years old, you can accurately claim you are twice their age.
Which of the following is a scale of measurement?
There are four scales of measurement:
Nominal, Ordinal, Interval, Ratio
.
What are the scaling techniques?
Definition: Scaling technique is
a method of placing respondents in continuation of gradual change in the pre-assigned values, symbols or numbers based on the features of a particular object as
per the defined rules. All the scaling techniques are based on four pillars, i.e., order, description, distance and origin.
What is ordinal scale of measurement?
Ordinal scale is
the 2nd level of measurement that reports the ranking and ordering of the data
without actually establishing the degree of variation between them. Ordinal level of measurement is the second of the four measurement scales. “Ordinal” indicates “order”. … It can be named, grouped and also ranked.
What is called measurement?
Measurement is
the quantification of attributes of an object or event
, which can be used to compare with other objects or events. … This system reduces all physical measurements to a mathematical combination of seven base units. The science of measurement is pursued in the field of metrology.
What are the 3 types of scale?
- Fractional or Ratio Scale: A fractional scale map shows the fraction of an object or land feature on the map. …
- Linear Scale: A linear scale shows the distance between two or more prominent landmarks. …
- Verbal Scale: This type of scale use simple words to describe a prominent surface feature.
What are the two types of scales?
There are two types of scales used in geography:
map scales and relative scales
. Each has a very different function, yet both also can work together.
What are four types of scales?
Each of the four scales (i.e.,
nominal, ordinal, interval, and ratio
) provides a different type of information. Measurement refers to the assignment of numbers in a meaningful way, and understanding measurement scales is important to interpreting the numbers assigned to people, objects, and events.
Why is IQ an interval scale?
An IQ (Intelligence Quotient)
score from a standardized test of intelligences
is a good example of an interval scale score. … IQ scores are created so that a score of 100 represents the average IQ of the population and the standard deviation (or average variability) of scores is 15.
