  I give a basic introduction to precision electroweak analysis, beginning with
calculation at tree-level which most simply illustrates the procedure. I then
work out the formalism for one-loop corrections to the vector boson self
energies (oblique corrections). This is a tractable subset of the complete
electroweak program. Not only does this exercise provide an analytically
accessible demonstration of the theory involved in electroweak precision
analyses, it also teaches students a useful technique to analyze a large class
of theories beyond the Standard Model.
