Tabulation involves arranging classified data in a systematic table with rows and columns. An effective table has a number, title, captions, stubs, body, head/foot notes, and source. The table example shows student details from Irshadiya College classified by gender, family, and residence type. There are general rules for preparing clear and useful tables, such as using a rough sketch, ordering elements alphabetically or chronologically, maintaining uniformity, avoiding excessive information, and distinguishing important entries. Tabulation simplifies complex data, facilitates comparison, presents data in proper perspective, and reveals patterns.
