Introduction: The aim of this investigation is to explore whether reflexes are better suing a preferred hand or non-preferred hand. The method of this conducting this experiment was using a ruler and dropping it between the index finger and thumb of the participants being experimented on and measuring the distance the ruler has been dropped. Technology was significantly utilised to provide visual representation of the results in graphs, boxplots and also provide the measures of central tendency and spread. The utilisation of technology also made the calculation of the results easier, hence the use of technology was highly recommended. The specific population chosen for this experiment were the male Year 11 students and a sample of 30…show more content…
Since the spread is not quite significant as 50% of the data were in a small range, thus the results were consistent therefore, it can be concluded that the mean gives an appropriate representation of the results. The boxplot and histogram of the non-preferred hand indicates that there was a significant spread between the results obtained, whilst the results also showed a symmetrical spread. Since there was a significant spread, the mean may not give an appropriate representation of the results obtained however, a large spread indicates that the results had large differences between the individuals experimented on. However, a higher percentage of the preferred hand would be above the mean as it is slightly negatively skewed, whilst the non-preferred hand is more symmetrical hence higher percentage of its results near the mean. The standard deviation of the preferred and non-preferred hand results were quite similar which indicates that the spread of the data were practically identical. The preferred hand data has 50% of its results in a range of 2.6 cm, thus indicating that the results were quite consistent as 50% of the results occurred in the range of 15-17.6 cm. Whilst the rest of the data was quite spread quite as the minimum was 8.6cm and the maximum was 21.6 cm, which is a range of 13 cm. Therefore the rest of data had been spread evenly as seen in the boxplot and
