(A) Selecting attributes of variables

(B) Developing Educational devices/Test

(C) Quantifying the attributes

(D) Determining operations to isolate the attributes

(E) Preparing standard scores

Choose the correct answer from the options given below:

The correct answer is - (A), (B), (C) and (D) Only

Key Points

• Selecting attributes of variables
  • The process of identifying which human abilities, personality traits, or interests to measure can be complex and subjective.
• Developing Educational devices/Test
  • Creating reliable and valid tests to measure these attributes requires careful planning and expertise.
• Quantifying the attributes
  • Assigning numerical values to abstract qualities such as personality or interest involves sophisticated psychometric techniques.
• Determining operations to isolate the attributes
  • It is challenging to develop procedures that can accurately isolate and measure individual attributes without interference from other factors.

Additional Information

• Preparing standard scores
  • While preparing standard scores is important, it is generally a step that follows the initial measurement and analysis of attributes.
  • Standard scores are used to interpret and compare individual scores within a normative framework.
• Psychometrics
  • This field focuses on the theory and technique of psychological measurement, which includes the development of tests and the quantification of attributes.
  • Key areas include test reliability, validity, and standardization.
• Validity and Reliability
  • Validity: Refers to the degree to which a test measures what it claims to measure.
  • Reliability: Refers to the consistency of a test in measuring an attribute over time.
