Mendoza et al. (2009) introduced a coin-rotation task as a convenient test of motor dexterity. It involves timed completion of t

wenty 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?

Answer

conceptual

Explanation

Manual dexterity is the ability of using your hands in a skillful way  thus manipulating objects and demonstrating small precise movements so as to come up with specific results or certain results. Manual dexterity is the abstract concept that the researcher wants to study so it is a conceptual variable. This is because the conceptual tells you the meaning of the concept . This tells you what your constructs are , and this is normally done by explaining how they are related to other constructs. Conceptual validity is a test measure that claims  to be measuring. Thus in measurement validity will measure what is supposed to measure .

Answer: divergent validity.

Explanation:

Divergent validity serves the goal of establishing construct validity by proving that a specific construct (e.g., motor dexterity) is different from other ones that could be present in the study (e.g., global upper-extremity strength). Divergent validity is necessary since it is usual to establish an operational definition for a construct that doesn´t involve only one construct.

marishachu [46]

It should be noted that players who have a high level of skill should not flaunt their skills in a game. Therefore, it's false.

A skill simply means the expertise or the talent that's required to perform a job. It should be noted that skills are important in sports for one to succeed.

Despite the importance of skills in sports, players with a high level of skill should not flaunt their skills in a game. It's important to be respectful to other players.
