Question

Find the range and standard deviation of the set of data190, 191, 192. 193, 194. 195, 196

Answer 1

The range is given for the comparison between the smallest and largest value from the set of data, in this case:

`\text{Range}=196-190=6`

The standar deviation is given for the following formula:

`S=\sqrt[]{\frac{\sum ^n_(i=1)(x_i-\bar{x})^2}{n-1}}`

In this case the standart deviation is 2.
