A live in and old house with 2 prong outlets and replaced them with self-grounding 3 prong outlets, but when I test them with a circuit analyzer it says that the ground is open. Did I do something wrong?

Unless you pulled a ground wire from the main box to the outlets, you have no ground and they will test as a open ground.

IF you installed two prong receptacles with 3 prong receptacles you must install a grounding conductor or protect that circuit with a GFI control protecting all receptacles on that circuit. 210-7-D

Good luck

What the heck is a "self-grounding outlet"? I've never heard of such a thing.

It's terminology referring to the fact that the outlet will ground itself through the yoke or strap when connected to a properly grounded box.

Pete is right.

A little more detail. self grounding receptacles are usually found in industrial setting where metal conduit is installed. The metal conduit serves as the grounding conductor. The self grounding receptalce eliminates the requirement of installing a pigtail to from the receptacle to the metal box completing the grounding circuit.
A self grounding receptacle has a little spring loaded clip that ensures constant contact with the steel box that is securely connected to the metal conduit used as the grounding conductor.
Self grounding receptacles sometimes are used in a Romex dwelling situation where the E/C connects the bare wire of the Romex to the steel box and then installs a self grounding receptacle to complete the circuit to the yoke of the receptacle.

Hope this helps
