Excel Project Three Excel’s automatic recalculation feature to complete what-if analysis Absolute cell references The if function Working with large worksheets

Using cell references When setting up a worksheet use as many cell references as possible in your formulas Cell references in a formula are called assumptions Change the assumptions, and you can change the output of your worksheet

Project Three Description Need: a worksheet and 3-D Pie chart showing projected monthly revenue, expenses, and net income Data: Projected revenues and assumptions based on historical data. Other values computed by formula Calculations: based on assumptions (page 3.06)

Series (p. 3.10) Series is mathematical term for a sequence of terms with some relation between them Relation generates the next term of the series Sequence can be numbers, dates, or another pattern Fill handle allows you to quickly set up and expand a series

Absolute vs. relative addressing When you copy cell references from one cell to another, Excel normally updates the cell reference Example: autosum on one column, then copy it one column over and references are updated

Absolute references Sometimes you want to include a single value in calculations in different parts of your spreadsheet You can “turn off” the Excel cell reference updating with absolute references (with $) See table p. 3.25

Entering formulas with absolute references Change to formulas version (CTRL + ACCENT MARK (`) Follow formulas on p Be careful, it is easy to make a mistake!

The if function Allows excel to examine a value and make a decision Make a logical test using comparison operators (p. 3.27) Has three parts Logical test The value if true The value if false

Excel as an analysis tool What-if analysis – change assumption, use undo to reset Goal seeking – allows you to analyze relationships between values in your spreadsheet and optimize a value

Summary of project three Using the format painter Creating a series with the fill handle Using absolute references in a formula Using the if function Entering the system date Adjusting assumptions Using goal seek

Summary cont. Selecting non-adjacent ranges for a pie chart Creating an exploding pie chart Freezing and unfreezing worksheet titles
