Significant Effect On Hand Dominance And Frustration Level With Occupational Tasks: Exemplar Essay To Follow

Motor-dexterity was tested, in order to determine the overall impact of hand dominance on individual behavior. This was tested by having individuals perform activities with each hand, and watch for signs of frustration as they use their non-dominant hand. The hypotheses were that: People would perform the motor-dexterity task faster with their dominant hand than their non-dominant hand, and that they would show more frustration while using their non-dominant hand.
The following findings indicate the significance, or effect of hand dominance on level of frustration. Data was collected from ten participants, with the researcher measuring how fast they could place 15 toothpicks into a mug with each hand. Both speed, and rate of frustration were recorded, then statistically studied for significance.
The average time for participants to complete the motor dexterity test ranged from 5 to 13, with an average of 6.25 seconds to complete the test. More specifically, the non-dominant hand was found to be, on average slightly slower than the dominant hand, with the non-dominant hand having a mean of 7, versus a mean time of 5.5 in the dominant hand. ‘
Past data indicates that time required to complete a given task is higher when trying to complete occupational tasks with the non-dominant hand. The hypotheses established is that μ1 –μ2< 0, where μ1 represents the mean of the dominent hand. This is to say that the mean time it takes to do the task with the non dominant hand is greater than the mean time it takes to compelte the same task with the non-dominent hand. A two-tailed T-test was conducted to compare the significance of the findngs, based on the null hypothesis that μ1 –μ2 > 0. Since we are looking for statistical evidence of an avereage shift to the negative side, the hypothesis is sufficient. The test concludes that since the P value is .401, then we must reject H0. As such, we can accept that there is substantial statistical evidence to indicate that tasks are performed more rapidly when performed with the dominant hand.
Similar calculations were performed to determine the impact of hand dominance on frustration level when performing an occupational task. The mean frustration level when performing the task was ENTER THE TOTAL MEAN, with the frustration level experienced while performing tasks with the non-dominant hand having a range significantly higher than, and thus a higher mean, than tasks performed with the dominant hand. Past data signposts that frustration level increases when trying to complete fine-motor skill type tasks with the non-dominant hand. The hypotheses established is that μ1 –μ2< 0, where μ1 represents the mean frustration level of an individaul while completing a task with the dominent hand. This is to say that the mean frustration level experienced when completing a task with the non dominant hand is greater than the frustration level expereinced when an individual compeltes the same task with the non-dominent hand. A two-tailed T-test was conducted to determine whether or not the observed differnce between frustration levels expereinced was of statistical significance, based on the null hypothesis that μ1 –μ2 > 0. This hypothesis is satisfactory, based on the assumption that the test is seeking evidence of a negative shift. The test concludes that since the P value is ENTER SECOND P VALUE HERE, then we must reject H0. As such, we can accept that there is substantial statistical basis for concluding that frustration level rises when a task is performed with the non-dominant hand.
