Create A Data Model
Muhtasari
A spreadsheet is a sheet of cells, arranged in rows and columns, that can store data and calculate with it. Behind every neat results table in a finance report or a school mark book sits a carefully built data model: the labels that name things, the values that hold the raw numbers, and the formulae that turn those numbers into answers automatically. Build the model well and the spreadsheet recalculates the moment you change a single figure, with no rubbing out and no arithmetic by hand.
In this lesson you will learn how to create and edit a model, how to tell a formula apart from a function, the order in which calculations are worked out, and the single most examined idea in the whole topic: the difference between relative and absolute cell referencing using the dollar sign. Master these and replicating a formula across hundreds of cells becomes a two-second job that always gives the right answer.
