This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

Problems associated with uncoordinated proliferation of data collection procedures will not be alleviated until educational agencies and legislative bodies, at both state and federal levels, view data as a scarce resource which must be managed efficiently. Better linkages must be made between the data transfer requirements generated by the…
