Organizing and visualizing data: data is orga(cid:374)ized a(cid:374)d visualized so as to reveal, glea(cid:374) i(cid:374)sight fro(cid:373) a(cid:374)d communicate the information, especially the main features and patterns, that are hidden within it, orga(cid:374)izi(cid:374)g -- tables, visualizi(cid:374)g -- graphs. A summary tabele indicates frequency, amount, percentage, or proportion in each category. Organzing is a table, visualizing is with a graph. Bar charts (one bar for each characteristic, represents the frequency) Pareto chart (bar chart, but with polygons (a line) that represents the cumulative percentage: the polygon is to show how much percentage of the information is distributed between how many characterstics. 3d pie charts are not good for displaying data.
