This symbol represents the average value of a distribution associated with a random variable.
This symbol represents the average value of a distribution associated with a random variable. It is difficult to determine empirically as we cannot access the underlying probability distribution function.
This symbol \(E\) represents the average value of an entire distribution associated with a random variable. It is difficult to determine empirically as we cannot access the underlying probability distribution function. Instead, we can sample values from the distribution and calculate the sample mean accordingly.
