This document discusses different methods of presenting statistical data, including textual, tabular, and diagrammatic presentations. It outlines the objectives of tabulation as presenting data simply and understandably, facilitating comparison and providing an overview. Tabular presentations can be simple one-way tables, double/two-way tables, or complex tables. Diagrams and graphs must follow rules for construction like proper scaling, proportions, titles and labels to be clear and simple. Common diagrams include bar diagrams that can be simple, sub-divided or show percentages, and pie charts. Common graphs are histograms, frequency polygons and ogives curves.
