Quantative reasoning - Speech or Presentation ExampleThis implies that half of the people of this group have a manual dexterity of over 79.5 and the another(prenominal) 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, afterwards 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 guide on 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 cartel the Standard deviation and the medial, Group B proves to be a better option. Thus these measures alone cannot be considered to make the choice. Other measures are to be unploughed in mind as well before making a decision by the attach to. Thus more data and analysis is requ ired for this decision.2. From the education 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 recurrent 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 higher up 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
