• Electronic spreadsheets were created in 1978 by Daniel Bricklin at Harvard Business School and Daniel Fylstra at M.I.T. and HBS as a study tool

• Spreadsheets are organized into columns and rows– Cells are where a row and a column meet– Cell address is the position of the cell– Range is a group of adjacent cells– Values are numbers or dates entered into a cell– Cell pointers or cursors are where the data is to be

entered

3-18

Spreadsheets

3-19

Spreadsheets

• Formulas, Functions, Recalculation, What-If– Formulas are instructions for calculations

• They define mathematically how one cell relates to another cell

• Example: =SUM(A5:A15) sums the values of the cells A5, A6, A7, and so forth up through cell A15

– Functions are built-in formulas, such as SUM()– Recalculation is the process of recomputing values– What-If analysis allows users to see what happens

to totals when one or more numbers change in cells• This is the powerful feature of spreadsheets over

manual calculations

3-20

Spreadsheets

• Charting and Analytical Graphics– Spreadsheets allow you to automatically

create graphs– When the cells change, the graphs change

too– Charts are a type of graph that include
