Hi I am a college student in wireless technology but am only very sketchy on statistics. I'm am trying to write a program to tell me if activity is unusual. I can read the activity of a person from a motion detector from day to day i.e.

mon activity - 250 times

tues - 300

wed - 400

thurs - 275

fri - 300

sat - 340

sun - 440

I've no problem getting mean = 329.3, stan dev = 68.7, median = 300

What i want to be able to do is find some algorithm to say that on day 8 if there is no activity (0) or very low that it is unusual or some confidence level. can anyone tell me any possiblilites or where I should be looking?
