What is the physical meaning of the expectation value of an observable?

What is the physical meaning of the expectation value of an observable?

The expectation value of the position operator is the average of the position measurements performed on a large number of identical systems. The expectation value of the Hamiltonian (i.e. energy) operator is the average of the energy measurements performed on a large number of identical systems.

What is the expectation value of a wave function?

This integral can be interpreted as the average value of x that we would expect to obtain from a large number of measurements. Alternatively it could be viewed as the average value of position for a large number of particles which are described by the same wavefunction.

What is the physical interpretation of wave function in quantum mechanics?

The physical meaning of the wave function is an important interpretative problem of quantum mechanics. The standard assumption is that the wave function of an electron is a probability amplitude, and its modulus square gives the probability density of finding the electron in a certain location at a given instant.

What is the expectation value defines?

The expected value (EV) is an anticipated value for an investment at some point in the future. In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values.

What is the difference between eigen value and expectation value?

from what i understand, an expectation value is the average value of a repeated value, it might be the same as eigen value, when the system is a pure eigenstate.. am i right? i) is the expectation value of over the state ; ii) if there exists such that , then is the eigenvalue of associated with the eigenstate .
