The question asks to identify the type of validity that concerns the degree to which a measure *obviously* involves the performance being measured. This relates to the surface-level appearance of the measure.
Let's examine the relevant types of validity:
The key phrase in the question is "obviously involves the performance being measured". This directly aligns with the definition of Logical validity (often referred to as Face Validity). It's about the common-sense appearance of the measure, whether it seems appropriate at first glance.
For example, a math test asking arithmetic questions obviously involves measuring arithmetic skills. This is logical validity.
Therefore, the type of validity that refers to the degree to which a measure obviously involves the performance being measured is Logical validity.
