The range is given for the comparison between the smallest and largest value from the set of data, in this case:
[tex]\text{Range}=196-190=6[/tex]The standar deviation is given for the following formula:
[tex]S=\sqrt[]{\frac{\sum ^n_{i=1}(x_i-\bar{x})^2}{n-1}}[/tex]In this case the standart deviation is 2.
