Q:
I viewed a physics lecture that identified the electron magnetic moment as 2.0115965218. I am not able to find any reference to this on the internet. The closest (similar) seems to be g/2 = 1.001 159 652 180, the electron anomalous magnetic moment. I assume these two numbers are related. Can you tell me how?

A:
Sharp eyes there. It looks like the lecture just gave the wrong number. The value for g/2 is correct.   The number in the lecture looks like a scrambled version of g.
