ABSTRACT
Using Available Data Finally, here is some advice about available data: The world is full of information, much of it there for the asking. Schools, businesses, newspapers, government units, health and welfare agencies, laboratories, test publishers, archives, stock markets, and many other sources have been collecting and banking information for years. The material may be in any form, from very limited, primitive filing systems to highly sophisticated technology exemplifying the most advanced storage and retrieval capability. Do not waste time generating data that are already available.
