Data sets and utilities from Project MOSAIC (<http://www.mosaic-web.org>) used
to teach mathematics, statistics, computation and modeling. Funded by the
NSF, Project MOSAIC is a community of educators working to tie together
aspects of quantitative work that students in science, technology,
engineering and mathematics will need in their professional lives, but
which are usually taught in isolation, if at all.
