Discussion:
The data in this experiment suggest that with dominant-hand practice, the performance of test subjects while using their non-dominant hand to complete the same task improved in their ability to minimize errors, but did not show enough evidence that the time it takes for them to complete the task was reduced. The p-values resulting from the statistical analysis of the data collected partially negated the hypothesis made before conducting this experiment because statistical significance was found with regard to error reduction, although not with regard to test completion time.
Weaknesses of this experiment include a lack of test subjects, and the lack of a flawless testing apparatus. A future study related to this one which could be performed would assess the ability of human beings to perform the same task with other parts of their body, i.e. their feet. The findings in this study, pertaining to hands, can only offer insight into transferable practice effects with regard to that single body part. The results may have been significantly different if another part of the human body were tested.
