I gotta go with the majority. If you hear something outside, try to see what it is FROM SAFETY. I am assuming you and yours are in the house safe or FAR away (meaning your daughter or wife isn't on their way home from somewhere when you hear these mysterious noises outside).
If you don't see anything stay alert, if you do see something call the police, make sure anyone in the house is safe and STAYS put. You put yourself in a safe defensive position and get ready to stand your ground if need be.
