Statistics — Table of Contents

Why do we bother with Statistical Diagrams?
► The answer to this question is similar to the one for: “why do we bother working out averages and measures of spreads?”.
► We live in a world jam-packed full of statistics, and if we were forced to look at all the facts and figures in their raw, untreated form, not only would we probably not be able to make any sense out of them, but there is also a very good chance our heads would explode.
► Statistical Plots (Diagrams) – if they are done properly – present those figures in a clear, concise, visually pleasing way, allowing us to make some sense out of the figures, summarise them, and compare them to other sets of data.

The chapter of Statistics completely consists of a parrent category, 4 children categories, a tag and 80 posts.
