Correct Answer - Option 1 : Both Statement I and Statement II are true

Statement I: Measurement is a set of rules for assigning numbers to represent objects, traits, attributes, and behaviors.

Explanation:

  • Measurement is the process of systematically assigning numbers to objects and their properties to facilitate the use of mathematics in studying and describing objects and their relationships.
  • Some types of measurement are fairly concrete: for instance, measuring a person’s weight in pounds or kilograms or his height in feet and inches or in meters.
  • Measurement is not limited to physical qualities such as height and weight. Tests to measure abstract constructs such as intelligence or scholastic aptitude are commonly used in education and psychology, and the field of psychometrics is largely concerned with the development and refinement of methods to study these types of constructs.
  • Scales of measurement refer to ways in which variables/numbers are defined and categorized.
  • Each scale of measurement has certain properties which in turn determines the appropriateness for use of certain statistical analyses.
  • The four scales of measurement are nominal, ordinal, interval, and ratio. 
  • Thus, the statement I is correct.

Statement II: A test is a procedure in which a sample of an individual's behavior is obtained, evaluated, and scored using standardized procedures.

Explanation:

  • A test is a device or procedure in which a sample of an individual's behavior is obtained, evaluated, and scored using standardized procedures.
  • A test provides a mechanism for making quantitative decisions about a process or processes.
  • The intent is to determine whether there is enough evidence to "reject" a conjecture or hypothesis about the process. The conjecture is called the null hypothesis.
  • Not rejecting may be a good result if we want to continue to act as if we "believe" the null hypothesis is true. Or it may be a disappointing result, possibly indicating we may not yet have enough data to "prove" something by rejecting the null hypothesis.
  • Thus, statement II is correct.

 

∴ Option I is the correct answer.
