Question

Mendoza et al. (2009) introduced a coin rotation task as a convenient test of motor dexterity. It involves timed completion of twenty 180° rotations of a nickel using the thumb, index, and middle fingers. Research participants' results on the coin rotation task are compared with their results on a test of grip strength — a measure of another construct: global upper-extremity strength. The correlation between the coin rotation task and the grip strength task were found to be not statistically significant.
This comparison provides support for which type of measurement validity? Group of answer choices
face validity
concurrent validity
discriminant validity
convergent validity

Answer 1

Answer: convergent validity

Convergent validity looks to refer to measure that whether what is being measured is up to standard.

The correlation between the coin rotation task and the grip strength task were measured against a standard that Mendoza et al has in mind already.
