Chapter 4
• This presentation covers the following:– Worksheets– Workbooks– Rows and Columns– Cells– Ranges– Relative referencing– Absolute referencing
A worksheet is essentially a page in a spreadsheet application that contains cells which are defined by rows and columns.
Each sheet can have it’s own name.
• A workbook is a collection of worksheets which are in the same spreadsheet.
• Different worksheets may contain data about different aspects of a business but together they form a workbook.
• A row is a range of cells that go across the spreadsheet.– Normally defined by numbers.
• A column is a range of cells that go down a spreadsheet.– Normally defined by letters.
• They can be altered in size and can even be hidden.
• This spreadsheet has hidden cells which contain calculated values that are used for presenting the information in the worksheet in a certain way.

• Cells are individual data stores which are identified by their column letter and row number.
• They can also be given names to make them easier to reference.
• Cells can also be formatted to represent data in different ways, e.g. Dates, currency, text, etc.
• They can also be formatted to display characters in different ways:– Colours– Fonts
• Cells can have borders, backgrounds, validation rules, alignment and conditional formatting.
• Basically it is a group of cells.
• The cells tend to contain similar data:– Test scores (as in the example)– Grades– Times– Etc
• When we want to use a value in a particular cell we need to reference that cell.
• There are two ways to reference a cell in a spreadsheet.
• Using:– Relative referencing– Absolute referencing
• Spreadsheets allow you to copy a formula from one cell to another.
• Relative referencing will automatically change the reference of the original cell by the number of cells you moved when you copied the formula.
• Look at this example:
• The original formula was in A3. It was copied across row 3. As the formula was copied the cell references updated across (so A1*A2 changed to B1*B2 etc)
• Absolute referencing is used when you want to copy a formula to another cell but you don’t want the cell references to change.
• An absolute reference is denoted by a $ sign.
• Look at this example:
• The cell reference with the $ sign has remained the same whilst the other cells (which are referenced relatively) have changed.
• You can also use named cells when you want to use absolute referencing.
• Look at this example:This cell has been called VAT.
• Describe how a cell could be used in financial spreadsheets?
• Describe what a range is and give an example of its use in the context of a football league table.
• What is meant by cell referencing?
• Explain the difference between relative and absolute cell referencing.
• Give two advantages of relative cell referencing and two advantages of absolute cell referencing.
