Whenever we are measuring any dynamical variable like position, momentum, energy etc in an identical condition for so many times we need quantum averaging of the results which is know as expectation value of the corresponding dynamical variable.

mathematically expectation value is determined as


<A>= <๐›น|A|๐›น>

A= dynamical variable

๐›น= Normalized wave function
