The measurement of human abilities/ personality/interest encounters problems in:

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:

Correct option is C

The measurement of human abilities, personality, and interest faces challenges in:

• Selecting attributes of variables (A): Deciding which attributes are most relevant to measure in educational or psychological contexts is complex.
• Developing educational devices/tests (B): Designing valid and reliable tests that effectively capture the desired attributes.
• Quantifying the attributes (C): Human traits like personality are difficult to quantify in a standardized way, which affects the accuracy of measurements.
• Determining operations to isolate the attributes (D): Identifying specific operations or methods to isolate and measure particular attributes (like intelligence or interest) is a key challenge in educational measurement.

Information Booster:

• The measurement of human characteristics is inherently complex due to their subjective nature and individual variability.
• Psychometrics and educational assessment tools strive to measure abstract traits, but challenges in accuracy, fairness, and validity often arise.

Additional Knowledge:

• Standard scores (E) are used to compare individuals' performances, but preparing standard scores does not directly affect the initial measurement problems of selection, development, and quantification of human traits.
