  We explore the measurement problem in the entropic dynamics approach to
quantum theory. The dual modes of quantum evolution---either continuous unitary
evolution or abrupt wave function collapse during measurement---are unified by
virtue of both being special instances of entropic updating of probabilities.
In entropic dynamics particles have definite but unknown positions; their
values are not created by the act of measurement. Other types of observables
are introduced as a convenient way to describe more complex position
measurements; they are not attributes of the particles but of the probability
distributions; their values are effectively created by the act of measurement.
We discuss the Born statistical rule for position, which is trivially built
into the formalism, and also for generic observables.
