The Average Temperature Problem

 Lets say you have a 6-room house.  You go and mount a temperature measurement device in each corner, plus the hallway of the home....amounting to 28 temperature readings.

All the room have one window....some have large windows....some two windows.  Some rooms face the north, some the west and some the south.  Some have trees affecting things.  Some heat ducts by the windows....some have heat ducts on the opposite side of the room. 

So over a 20-year period, can you say with any scientific authority....there's an average for the house....with a value that you'd put trust in?  

After a long pause.....you'd likely state that weather affected yearly temperatures...having windows open affected temperatures....having the temperature changing....there is NO average of value.

I see the same problem with people trying to say the Earth has an average  temperature, and you can reach some scientific level of 'trust'.  

Math Word Problem

 My construct:

X-high school (9th to 12th grade) has 800 students and has 34 teachers consuming 2.475,000 in pay/benefits).

Only 200 students are able to maintain a A or B level on grades.  400 students maintain a C or D level.  And the remaining 200 students are in failure status.

So my question is...what is the question and answer?

Logically, after you consider the whole math problem....why would you keep nine teachers or 200 students?  Cut the teachers and students, and save $675,000.  

I might give the students a 'warning' for three months but after that....why would you continue 'limping' along with a waste of time.  BK and McDonalds needs burger flippers.....send these 200 kids out into the flipper world. I might give each kid some small part of the saved $675,000....as a parting gift....just to show my kind nature.
