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
