Depends on where it is broken. Most spark plugs I see broken are AC Delcos and they break flush with the top of the threads just above the sealing flange. If the porcelain is gone as well you should have a hole directly into the cylinder. If this is the case DONT drill it. It just creates debris into the cylinder. There is an easier way to remove it. Snap-On Tools has a great set of tapered easy outs that remove these relatively easy. A little bit of heat from a propane torch applied on the broken piece can free it up a little too before you insert the easy out. Hope it goes well for you

If just the ceramic part is broken off before the nut, remove it like you would an undamaged spark plug.
If you mean snapped off past the nut, you can try drilling a big hole in it and using an Easy Out. Since you don't torque spark plugs very tight, it will probably come out very easy, but you might leave debris in the cylinder if you've drilled too far, which would be very bad.
If you're in doubt about whether you've left debris in the cylinder, about your only safe option is to remove the head.
Take a look at a cross-section of a sparkplug to evaluate whether you think you can drill a hole in it and successful remove it. (see link below)

drill a hole that you can fit a screw and screw it out
