mode, lol, to calculate ur average gas bill add up all pevious prices (over the last 8 years) and divide by the amount of prices u have added up (8). That gives u ur average bill. To find the total cost u just add them up, no median of mean (wtf r u on about)
Be carefull though your gas prices are probably increasing ; you are not just more likely to use more gas but also gas prices are rising.
Mate, it's not hard, I'm 14 :(

Is the mean and median of a data set always near to being equal?
Only if the data are symmetrical.========And to illustrate the above:Imagine a bus that has 3 passengers on it, all of whom work at a factory earning £15,000 per year. If we consider the mean and median salary of the passengers then here they will be identical as the data is perfectly symmetrical.However, now suppose Bill Gates (who of course earns a vast salary!) got on this bus at the next stop. With these 4 passengers, suddenly the mean salary has now increased dramatically, yet the median salary remains unchanged at £15,000.
