I have following inputs
Sum of the squares of the numbers. For example if the numbers are $1,4,6$ the sum of squares is $53 = 1^2+4^2+6^2$.
And I have the number of input samples: $3$ in this case. Is it possible to calculate the standard deviation?
Note I don't have the actual numbers $1,4$ and $6$ just the sum of their squares that is $53$.
You might note that e.g. $1^2 + 8^2 = 4^2 + 7^2$. Do $\{1,8\}$ and $\{4,7\}$ have the same standard deviation?
