Solutions
Expert Solution
summary:
As we know variance for given data is larger than mean because of presence of some outliers. In given example a observation 27.3 is very far from other observations because of this we have larger variance. Also we know standard deviation is most important and widely used in measure of dispersion. It is also least affected by fluctuations of sampling.
