Let $$S$$ be the standard deviation of $$n$$ observations. Each of the $$n$$ observations is multiplied by a constant $$c.$$ Then the standard deviation of the resulting number is
Consider any set of 201 observations $${x_1},{x_2},.....\,{x_{200}},\,{x_{201}}.$$ It is given that $${x_1}\, < \,{x_2}\, < \,.....\, < {x_{200}}\, < {x_{201}}.$$ Then the mean deviation of this set of observations about a point $$k$$ is minimum when $$k$$ equals
