Study Notes
Validity of Measurement
- Validity is crucial in evaluating a measurement procedure, ensuring it accurately measures what it claims to.
- It's challenging to measure hypothetical constructs, leading to questions about validity.
- For instance, intelligence is a hypothetical construct measured through observable behaviors.
- Face validity relies on subjective judgment and superficial appearance, asking if the measurement technique appears appropriate.
- Concurrent validity compares a new measurement method to a well-established one, checking for consistency between scores.
- High correlation between the two procedures suggests the new method is also valid but doesn't ensure they measure the same thing.
- Although concurrent validity can be established, it doesn't necessarily guarantee the measurements are identical.
Face Validity
- Face validity is the least scientific definition of validity.
- It assesses whether a measurement procedure appears to measure the intended variable.
- While subjective, it can be problematic if the research participants understand the purpose, potentially influencing their responses.
- Researchers may use disguises to conceal the true purpose of measurements.
Concurrent Validity
- Demonstrates that the scores from a new measurement method correlate with scores from a well-established method.
- This suggests both measurements capture the same variable.
- However, even with a strong relationship, the measurements may not be measuring identical aspects of the variable.
- Establishing concurrent validity doesn't necessarily mean the new measurement procedure has the same level of validity as the well-established one.
