  2. What is a Spreadsheet? A spreadsheet ... • is an application software package • can store and manipulate large amounts of data • is an electronic version of a ledger • consists of a grid from columns and rows • is a computation tool • can accurately compute mathematical formulas • has the ability to create charts and graphs • can be used to create a tables

  3. A spreadsheet is ... the electronic version of a ledger. It is a grid made from columns and rows. The nice thing about using a spreadsheet is that you can experiment with numbers without having to RE-DO all of the calculations!

  4. USES OF SPREADSHEETS • Record Keeping • Analyze data • Forecasting - asking “what if” questions

  5. Basics of a Spreadsheet • Spreadsheets are made up of • columns • rows • cells

  6.  COLUMNS…  COLUMNS go vertically - up and down. They are defined by Letters which go across the top of the grid.

  7.  ROWS…  ROWS go horizontally - left to right Rows are defined by Numbers which go down the left side of the grid.

  8. CELL... The CELL is the space where the column and the row intersect. B6 The CELL is named according to its Column letter and Row number. It is where the information is stored.

  9.  Types of Data  Cellscan contain four types of data. LABEL - anything that is just text ex. Title or Items or Cost VALUE - any number ex. 8 or 3.14 or -59.6 FORMULA - math equation ex. =8*5 or =6+8/4 FUNCTION - built in formula ex. =SUM(A1:A5)

  10.  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.

  11.  VALUES  Values are used to enter FIXED number data. A value can be any kind of specific number: currency, percent, decimal ...

  12. # Working with VALUES # When you are working with values, you must use the appropriate symbols. + is the symbol foraddition -is the symbol forsubtraction *is the symbol for multiplication /is the symbol for division

  13.  FORMULAS  Formulas are equations that performs calculations. All formulasMUST BEGIN with an equal sign (=). A formula will be displayed on the screen as a number, but the formula bar will show the formula.

  14.  FUNCTIONS  Functions are built in equations that perform calculations automatically All functionMUST BEGIN with an equal sign (=). A function will be displayed on the screen as a number, but the formula bar will show the function.

  15. FEATURES OF SPREADSHEETS • Variable column width - you can change the width of columns • Click on the line between columns and drag • Go to Format, Column, Width • Go to Format, Column, Autofit - adjusts column to largest entry • Automatic spill over • only works on labels, not numbers • Sorting • Alphabetical and Numerical

  16.  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! Examples: Pie charts Bar graphs Line graphs

  17.  Charts or Graphing  chart sheets – the chart exists on a separate sheet in the workbook embedded charts – the chart exists as an object in the worksheet alongside the data legend – identifies each data series in the chart

  18. ADVANTAGES OF SPREADSHEETS • Ability to store data and formulas • Ability to recalculate • Speed • Accuracy

  19. POPULAR SPREADSHEET PACKAGES • Microsoft Excel • Quattro Pro • Lotus 1-2-3

  20. Axis X axis – horizontal axis Y axis – vertical axis
