Is standard deviation defiined for Hamming norm












1












$begingroup$


Is there a way to define the concept of standard deviation for binary norms like Hamming norm?



For two words (in most general case - sequences of symbols from a given alphabet) of the same length, Hamming norm gives a number of different letters. If we have a series of words $A = { x_i }$, $i = 1, ..., N$, and also a reference word $x_0$, we can measure Hamming distance $H_i$ between each word $x_i$ and reference word $x_0$.



How can we introduce a concept of average word $langle x rangle$ to then come to a definition of standard deviation which would characterise how individual words $x_i$ are scattered?
