Averages allow you to see through variability. An average is a surprisingly stable but delicate figure. For instance, you could have a 3 month average of highly variable data equalling $100/mo, but you could add 10 years worth of highly variable data to the 3 months of data, and still have a result of $100/mo
Accuracy.
To get a better estimate.
Structuralism
They are centre to centre, but given the relative measures and the fact that the distances are averages over elliptical orbits rather than circular ones, the difference between the two is irrelevant.
Think of a plastic bag filled with water. It makes more sense to describe the amount of water within the bag by it's volume vice the bag's dimensions.
You get an accurate answer with it rather than using semi quantitative methods to get estimated results.
They do not. They can represent definite numbers just as well and definite numbers can be averages.
It may be possible to generalise results to other integer values.
Evolution is a gradual process that occurs through natural selection. Natural mutation results in some offspring.
Aluminium oxide is an example of corrosion of advantage rather than disvantage

People work out averages to get a general sense about something. An average will also allow a person to put findings in a group rather than having a bunch of separate findings.
I would rather be paid a steady salary than be paid by results
For heat loss to be an advantage to humans rather than a disadvantage, the heat lost must be equal to that produced.
When a person talks to a person or a few persons directly rather than a large group or an audience. When written, an individual communication is a letter to an individual rather than a reproduced mass mailing. This answer is an individual communication in that it is an original answer written for this question.
They had smaller, faster ships that were a big advantage rather than Spain's ships.
Science means more of research and an individual's role in research is tremendously great. Team research is also often heard of. But the discoveries so far seen on this planet earth are more of individual contributions rather than the team works. You are at your liberty to work individually and come up with your results.
