------------------------------------------------ Find the range and standard deviation of the set of data:

190, 191, 192, 193, 194, 195, 196

Answer :

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.
