Data need to be organized in some way to make sense and be useful. Data by itself is meaningless without interpretation, and it is interpretation that turns data into information.
With personal computers and affordable statistical software these day,
it is possible to create visual displays quite easily. A very simple statistical software package
that can do a lot is CDC & WHO’s Epi Info.
This is a free software program. Its latest version, 6.04b, is downloadable from the
CDC Web Site.
Andrew Dean & his colleagues are working on a Windows-based version, Epi2000, that is currently undergoing beta testing.
