Spreadsheets and Charts A Beginners Guide
What is a Spreadsheet? A spreadsheet... is an electronic version of a ledger consists of a grid from columns and rows is a computation tool helps organize, display, and manage information has the ability to create charts and graphs can be used to create a tables
A spreadsheet is... the electronic version of a ledger. The nice thing about using a spreadsheet is that you can experiment with numbers without having to RE-DO all of the calculations! It is a grid made from columns and rows.
Basics of a Spreadsheet Spreadsheets are made up of –columns –rows –cells Each cell contains a type of data –text –number data –formulas
COLUMNS… COLUMNS go vertically - up and down. They are defined by Letters which go across the top of the grid.
ROWS… ROWS go horizontally - left to right Rows are defined by Numbers which go down the left side of the grid.
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. B6
Types of Data Cells can contain three types of data. LABEL - anything that is just text ex. Title or Items or Cost FORMULA - math equation ex. =8*5 or =6+8/4 CONSTANT - any number ex. 8 or 3.14 or -59.6
LABELS LABELS help us identify what the numbers stand for… they help us understand the spreadsheet. LABELS are text entries - they have no numerical value.
CONSTANTS Constants are used to enter FIXED number data. A constant can be any kind of specific number: currency, percent, decimal...
Calculating 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
FORMULAS Formulas are equations that performs 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.
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! ) (
IF Function Example of IF=IF (A3>70, Pass, Fail) ComparesIs Cell A3 greater than 70? Answer If Cell A3 is greater than 70, then it will print Pass. If Cell A3 is less than 70, then it will print Fail.
Charts or Graphing You can use the Chart Wizard to help you make a chart or graph. There are 16 types of charts you can choose from. The type of chart you pick usually depends on the data you are using! For more information on Charts go to:
Dont Forget!!! Like ANY tool, a spreadsheet should be used to aide in producing a polished product and NOT become the product. - Teacher Created Materials
