Is there a name for this method of data consolidation / reduction?

Say I have a data series of N elements.



I want to create second series that represents a rough approximation of the first series with a reduced set of elements M.



Question 1: Is there a proper name for the general set of techniques used to accomplish this?



Question 2: Is there a specific name for the following technique or similar techniques?



1 - Divide N / M, which produces a number of elements per bucket B.



2 - Calculate mean for first B elements. Calculate mean for second set of B elements.. so on and so forth.

          The word describing this process is called "downsampling". Sometimes referred to as "decimation".



          Having come from a 3D background, I am familiar with reduction of points in a 3D mesh as "decimation". The terms seem to be used similarly in fields of computer graphics, communications, and economic analysis.
