Functions Defined by Data
Part 6: Summary
In this module we have explored
functional relationships represented by sets of discrete data: first-class
postage as a function of time, numbers of AIDS cases as a function of time,
and Federal deficits as a function of time -- or perhaps substitutes for
these from the optional data sets in Part 5.
Be sure you are familiar
with the commands in your computer algebra system for carrying out the
following basic operations:
- Entering sets of paired
data.
- Plotting functions or relations
determined by paired data.
- Adjusting or adapting plots
to get as much information as possible from them.
If you are not sure how
to do any of these things, you should review appropriate parts of the module.
In addition, you should
have at least an intuitive sense of how to extract information from both
numerical tables and scatter plots, and you should be developing your ability
to express this information and your judgments about it in complete sentences
and paragraphs. In subsequent modules we will work on more systematic ways
to analyze information and make judgments.
