By the end of this set of exercises, you should be able to
(a)
extract and interpret data from bar charts, line graphs, pie charts
and stem-and-leaf diagrams, and interpret trends in graphs.
(b)
construct bar charts, line graphs, stem-and-leaf diagrams,
and scattergraphs (scatter diagrams) from given data.
Also, draw a best-fitting line by eye on a scattergraph and use
it to estimate the value of one variable given the other.
