Overview<br />
Before conducting a statistical analysis, you can use graphs to explore data and assess<br />
relationships among the variables. Also, graphs are useful to summarize findings and<br />
to ease interpretation of statistical results.<br />
You can access MINITAB’s graphs from the Graph and Stat menus. Built-in graphs,<br />
which help you to interpret results and assess the validity of statistical assumptions,<br />
are also available with many statistical commands.<br />
Graph features in MINITAB include:<br />
■ A pictorial gallery from which to choose a graph type<br />
