Objectives• Design a Worksheet for What-If

Analysis• Answer What-If Questions by

Changing Values in a Worksheet• Chart Data with a Line Chart

with Microsoft® Excel 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 18

Design a Worksheet for What-If Analysis

• Percentage rate of increase– The percent by which one number

increases over another number– Amount of increase/base

with Microsoft® Excel 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 19

Design a Worksheet for What-If Analysis

• Excel order of operations– Expressions within parentheses first– Exponentiation, if present, before

multiplication and division– Multiplication and division before addition

and subtraction– Consecutive operators with the same level

of precedence calculate left to right

with Microsoft® Excel 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 20

Design a Worksheet for What-If Analysis

• Calculate a value given the increase– The result when one number is increased a

certain percentage• Base * (100% + percent increase)

Chart Data with a Line Chart

• Line chart– Displays trends over time– Displays time along bottom axis– Connects data points with a line– Illustrates trends through curve and

direction of line
