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

A spreadsheet ...

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.

•Record Keeping

•Analyze data

•Forecasting - asking “what if” questions

Spreadsheets are made up of◦columns◦rows◦cells

COLUMNS…

COLUMNS go vertically - up and down.

They are defined by Letters which go across the top of the grid.

ROWS go horizontally - left to right

Rows are defined by Numbers which go down the left side of the grid.

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

Cells can contain four 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

VALUE - any number

ex. 8 or 3.14 or -59.6

FUNCTION - built in formula

ex. =SUM(A1:A5)

LABELS help us identify what the numbers stand for… they help us understand the spreadsheet.

LABELS are text entries - they have no numerical value.

Values are used to enter FIXED number data.

A value can be any kind of specific number:

currency, percent, decimal ...

When you are working with 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

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 formula bar will show the formula.

Functions are built in equations that perform calculations automatically

All function MUST BEGIN with an equal sign (=).

A function will be displayed on the screen as a number, but the formula bar will show the function.

•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

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

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

•Ability to store data and formulas

•Ability to recalculate

•Speed

•Accuracy

•Microsoft Excel

•Quattro Pro

•Lotus 1-2-3

X axis – horizontal axisY axis – vertical axis
