Quantative reasoning - Speech or Presentation Example This implies that half of the people of this group have a manual dexterity of over 79.5 and the other half of the employees have a manual dexterity of over 79.5. To calculate the standard deviation of Group A, firstly the difference of the values and the mean is calculated, after which these numbers are squared. The total of the squares are then calculated and then divided by the number of values to provide the Variance. The last step is to take the square root of the variance. This provides the standard deviation for the group. The Standard deviation along with the Mean, give the image of Group A to be a better option, whereas combining the Standard deviation and the median, Group B proves to be a better option. Thus these measures alone cannot be considered to make the choice. Other measures are to be kept in mind as well before making a decision by the company. Thus more data and analysis is required for this decision. 2. From the information that has been provided the Mean has been calculated to be 7.55 calls. For the mode however there are two possible answers, 4 as well as 8. This is because they are repeated the most number of times. However, 8 will be chosen as the Mode in this case as it is closer to the mean that has been calculated. The Median for in this case has been calculated to be 7. These numbers are quite accurate and are as expected. These values are all quite accurate, however the median can be considered as the most accurate measure. The Standard Deviation in this case has been calculated as 4.421255. This implies that the number of calls can be 4.421255 Â ­above or below the calculated mean. This deviation is considered to be good as the deviation is not very high and allows a clearer view of the number of calls the company can
