Re: average temperature

Someone answered a while ago that the average daily temperature is the average of 24 hourly temperatures. This may be how it is calculated, but it isn't quite right.
Suppose you are in a new building with stateoftheart heating and cooling controlled by a computer. Because the bugs aren't out of the system yet, your office is heated to 90 degrees all the time except just before the hour, when the air conditioning kicks in and reduces the temperature to 50 degrees just in time for the hour to strike. Then the office is rapidly heated back to 90 degrees.
Suppose you measure the temperature on the hour for your average temperature. Will this give you a reasonable average daily temperature? Why? What would be a better way? Have I given enough information to really compute the average temperature?
(Hint: the best average temperature calculation uses ideas from calculus.)
