  1. There is a statistically significant correlation between the having high score (high dexterity) for the Purdue Peg Test and time for completion of the tool clearance for the 3rd trial; and hammering the nail and screwing the screw for the first and third trials. There is a statistically significant correlation between number of words formed and a low number of symptoms on the NSI.
