CHAPTER OVERVIEW

What is a Spreadsheet?

Introduction to Microsoft Excel:

Objectives Describe what a spreadsheet is and potential

applications Distinguish between a formula and a constant Open, save, print a workbook; insert and delete

rows and columns Distinguish between a pull-down menu, shortcut

menu and toolbar Print worksheet with values or formulas Use Page Setup to print worksheet and preview

before printing

Overview Introduction to Spreadsheets and

Excel Show wide diversity of spreadsheet

applications Fundamentals of spreadsheets using

Excel Worksheet recalculates

automatically after changes

Spreadsheet Basics

Spreadsheet is a computerized ledger

Divided into Rows and Columns Cell References Constants--entries that do not

change Formulas--combination of constants

and functions

Excel Basics

Common user interface on all Office 2000 applications

Worksheet is an Excel spreadsheet Workbook contains one or more

worksheets Toolbars--Standard and Formatting File menu--Save, Open and Print

commands

Excel 2000

Excel 2000 Worksheet

Modifying the Worksheet

Insert Command To add individual cells, rows or columns

Modifying the Worksheet

Delete Command To delete individual cells, rows or columns

Modifying the Worksheet

Page Setup Commands Portrait versus Landscape, Margins,

Header/Footer, and Sheet Tabs

Gaining Proficiency:

Copying, Formatting and Isolating Assumptions

Objectives Explain importance of isolating assumptions Define, select and deselect cell ranges Copy and move cells; differentiate between

relative, absolute and mixed addresses Format a worksheet Change column widths Insert a hyperlink and save as web page

Overview Basic commands to create a worksheet Use cell ranges and commands to build a

worksheet Isolate assumptions to easily evaluate

alternatives Improve appearance of worksheets Accuracy is critical for spreadsheets Introduce relationship of Office 2000 and

the Internet

Getting around the Worksheet A rectangular group of cells is a

range Copy duplicates contents of a cell

from a source range to a destination range

Three types of addresses: absolute, relative and mixed

Move transfer contents of a cell

Excel 2000 Formatting

Column widths Row Heights Numeric Format Alignment Fonts Borders, Patterns, and Shading

Numeric Formats

General Number Currency Accounting Date Time

Percentage Fraction Scientific Text Special Custom

Format Cells Command

Spreadsheet In Decision Making:

What If?

Objectives Use spreadsheets in decision making; use Goal

Seek and Scenario Manager Use PMT function Use Paste Function Use fill handle and AutoFill capability Use AVERAGE, MAX, MIN, and COUNT functions

in a worksheet Use the IF function to implement a decision and

explain how the VLOOKUP function is used Print and view large spreadsheets

Overview Learn to use spreadsheets as a tool in

decision making Use financial and statistical functions Calculate different results with the

Goal Seek command Choose between multiple sets of

assumptions with Scenario Manager Use relative and absolute cell

references

Analysis of a Car Loan

Can I afford it? How do I calculate

for: rebates down payments interest rates years of loan

Using a Worksheet for Analyzing a Car Loan

Set up a worksheet template with initial conditions

Use a PMT function which requires interest rate/period, number of periods, and amount of loan

Use Goal Seek to set an end result

Setting up Goal Seek

Establish PMT interest rate term down payment

Use Goal Seek change result

changing one variable

PMT Function A predefined formula that accepts one or

more arguments as input, performs the indicated calculation and returns another value as output

Goal Seek command Enables us to set an end result in order to

determine the input to produce that result

Setting up Goal Seek (Cont…)

Excel Features

Relative (a cell reference that changes during

a copy operation) versus Absolute(one that

does not-absolute) addressing in a worksheet

Using the fill handle to copy Pointing to cell address for formulas

or functions is more accurate Using the Paste Function and the

Formula Palette

Statistical Functions--MAX,MIN, AVERAGE, COUNT and COUNTA

Use functions over arithmetic expressions

IF function enhances decision making VLOOKUP(vertical lookup) Function

and its use

Using Functions in Excel

Managing a Large Worksheet

Scrolling shows specific rows and columns

Freezing Panes keeps headings in sight

AutoFill capability enter series into adjacent cells

Scenario Manager enables evaluation of multiple conditions

Graphs and Charts:

Delivering a Message

Objectives Know advantages and disadvantages of

different chart types Use the ChartWizard Use Drawing toolbar to enhance chart

with lines, 3D shapes and objects Differentiate between data series specified in

rows versus ones in columns Understand how charts can be accurate

statistically yet misleading conceptually Create a compound document consisting of word

processing, worksheet and a chart

Overview Business graphics one of most

exciting Windows applications Determine message of chart Create charts using Chart Wizard Plot multiple data sets on a single

chart Dynamically link a chart to a memo

Chart Types

Always remember to keep it simple Pie and Exploded pie charts,

effective for displaying proportional relationships

Column chart used for number display

Bar charts show numbers horizontally

Pie and Exploded Pie Charts

Column Charts

Creating a Chart

Use the Chart Wizard a four step process Step one choosing a chart Step two review data series Step three final touches Step four where to store

Chart Wizard

Finishing the Chart Embedding in a worksheet or

separate chart sheet Enhance with Drawing toolbar

Using the Drawing toolbar

Multiple Data Series What message do you want chart to

display Rows versus columns

If data series are in rows the Chart Wizard will use first row for X axis and use first column for legend text

If data series are in columns the Chart Wizard will use first column for X axis and use first row for legend text

Using Multiple Data Series

Object Linking and Embedding

Office 2000 makes it easy to create a compound document

Embedded object is stored in the compound document

Linked object is stored in its own file and used with a compound document

OLE pronounced “Oh-lay”

Compound Documents

Additional Chart Information

Excel has 14 standard chart types on the Chart Wizard

Line used to display time-related information

Combination uses two or more charts

Use Accurate Labels Don’t add Dissimilar Quantities

A Combination Chart
