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?
