Transcript of SC ICT Certification Level 1 07 Spreadsheets By Ross Parker.
Spreadsheet• wikipedia.org: “A spreadsheet is a
computer application that simulates a paper worksheet. It displays multiple cells that together make up a grid consisting of rows and columns, each cell containing either alphanumeric text or numeric values. A spreadsheet cell may alternatively contain a formula that defines how the contents of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated.”

Saving and conversion
• Save regularly• Organise files using folders• Many formats:
– .xls– .xlsx– .ods– .csv
• .xls is defacto standard• Standards are not always compatible
Current worksheet tabs
Tabs• wikipedia.org: “In the area of graphical user
interfaces, a tabbed document interface (TDI) is one that allows multiple documents to be contained within a single window, using tabs to navigate between them.”
• Tabs are becoming more prominent in computing, but are a staple of spreadsheets.

Printing
• Print only when needed.• Consider:
– Which printer– Split sheet into pages– Quality– Color vs greyscale– Duplex– Page Range– Number of copies– Pages per sheet
• Cells are referred to by:– Letter (horizontal axis)– Number (vertical axis)
• If a cell is copied, references are updated relative to the new location.– To prevent this, use the $ symbol
• Cell reference to other sheets• Cell reference to other documents
Cell reference
This is cell B2
This is cell $B$2
Formulas
• Formulas allow data to be manipulated.• Some sample formulas:
=1+2+3+4+5
=A1+B1
=SUM(C1:C6)
=AVERAGE(C1:C6)
=IF(C6=42,"Y","N")
• Formulas can be “nested”=IF(C6=42,AVERAGE(C1:C6),"N")
• Troubleshooting formulas is tough
