Question

The accuracy of the measurement provided by an instrument is determined by comparing the reading on the device with a standard measure. This procedure is known as establishment of:

• A. Construct Validity
• B. Content Validity
• C. Criterion Validity
• D. External Validity

Hint:

Compare with Gold Standard → Criterion Validity

Answer 1

The Correct Option is C

Concept:
Validity refers to how well a test or instrument measures what it is intended to measure. There are different types of validity:
• Construct validity: Measures theoretical constructs
• Content validity: Ensures content covers entire domain
• Criterion validity: Compares with a gold standard
• External validity: Generalizability of results

Step 1: Understanding the question.
The question states:
• Measurement is compared with a standard measure
• Accuracy is determined

Step 2: Identifying key concept.
When a measurement is compared with an already established gold standard, it evaluates:
• How closely it matches the standard

Step 3: Matching with validity type.
This directly corresponds to:
• Criterion validity

Step 4: Eliminating other options.

• Construct → theoretical concept, not comparison
• Content → syllabus coverage
• External → applicability to population

Step 5: Conclusion.
\[ \boxed{\text{Criterion Validity}} \]
