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

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

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
