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.
