Dealing with Data: A 'Simple' Linear Fit [Note: The activities
in this module make reference to the computer algebra system
(CAS) Maple. Any other CAS can be used instead (e.g.,
Mathematica, Mathcad, etc.) as long as the user is familiar with
that CAS system. In other words, while preferred here, Maple is
not required for the use of this module.] The first true test of
any scientific theory is whether or not people can use it to
make accurate predictions. Calculus, being the study of
quantities that change, provides the language and the
mathematical tools to discuss and understand change in a
precise, quantitative way. An important prerequisite to using
calculus to analyze "real-world" situations is having a good
understanding of the basic "elementary" functions: polynomials,
logarithms, trigonometric functions, and all their compositions,
inverses, etc. With an understanding of the calcul
