1. What is a Spreadsheet? A spreadsheet…………………………….. Is an electronic version of a ledger Consists of a grid from rows and columns Is a computation tool Can accurately compute mathematical formulas Helps organize, display and manage information Has the ability to create charts and graphs Can be used to create a table

2. A spreadsheet is the electronic version of a ledger.  It is a grid made from columns and rows A B 1 computer ledger computer ledger 2 car loan $12,000.00 3interest9.60% 4 #of payments 60 5 6 Monthly Paymt. $252.61 The nice thing about using a spreadsheet is that you can experiment with numbers without having to RE-DO all of the calculations

3. Basics of a Spreadsheet  Spreadsheets are made up of -columns-rows-cells Each cell contains a type of data -text -number data-value -formula

4. Columns  Columns go vertically –up and down.  They are defined by Letters which go across the top of the grid.

5. ROWS  ROWS go horizontally –left to right  Rows are defined by Numbers which go down the left side of the grid.

6. CELL  The CELL is the space where the column and the row intersect.  The CELL is named according to its Column letter and Row number.  It is where the information is stored.

7. Types of Data  Cells can contain three types of data. Label –anything that is just text ex. Title or Items or Cost Constant (Value) –any number ex. 8 or 3.14 or -59.6 Formula –math equation ex. 8*5 or 6+8/4

8. LABELS  Labels help us identify what the numbers stand for…  Labels are text entries –they have no numerical value.

9. CONSTANTS Values  Constants (values) are used to enter FIXED number data.  A constant can be any kind of specific number: currency, percent, decimal

10. # Working with Constants#  When you are working with constants or values, you must use the appropriate symbols. + is the symbol for addition -is the symbol for subtraction * is the symbol for multiplication / is the symbol for division

11. FORMULAS  Formulas are equations that perform calculations.  All formulas MUST BEGIN with an equal sign (=). A formula will be displayed on the screen as a number, but the entry bar will show the formula.

12. A Few Formulas  Suppose you had a spreadsheet showing test grades… you might use the following formulas. To FindUse Total Scores=sum(__:__) High Score=max (__:__) Low Score=min (__:__) Average Score=average (__:__) Total # of Scores=count (__:__) (It will not count text entries or blank entries)

13. IF Function  Example of IF =IF (A3>70, “Pass”, “Fail”)  Compares Is Cell A3 greater than 70?  Then it will print Pass.  If cell A3 is less than 70,  Then it will print Fail.

14. Charts or Graphing  You can use the Chart Wizard to help you make a chart or graph.  There are 16 different types of charts you can choose from. The type of chart you can pick usually depends on the data you are using!
