  • 1. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Objectives: Introducing the basic concepts of spreadsheets. What Is a Spreadsheet? A spreadsheet lets you manipulate numbers. You can add, subtract, multiply, divide, or perform other calculations on the numbers that you enter. You can also format your numbers and produce charts that base on your numbers. 100 80 60 Chin 40 Eng 20 Maths 0 Simon Peter David Tony You may use different types of charts to help you analyze your data. 250 200 150 Maths 100 Eng 50 Chin 0 Simon Peter David Tony Electronic spreadsheets help you organize you data and analyze the results. In addition, electronic spreadsheets are faster, more efficient and produce less errors than ordinary calculators.Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 1 Published by T.

  • 2. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Row, Column & Cell A spreadsheet document (or a worksheet), typically appears on the screen as a grid of numbered rows and alphabetically lettered columns. A cell is a box where you can enter data into your spreadsheet. The box representing the intersection of a row and a column is called a cell. A row is a horizontal line of cells, and a column is a vertical line of cells. Cell Address Each cell has a unique cell address to define the location of the cell. The cell address usually includes the column letter followed by the row number. For example, the cell in the upper-left corner of the worksheet is called cell A1. The active cell usually has a dark or thick border. Active Cell Data is entered into the active cell (or current cell). The active cell usually has a dark or thick border (e.g., cell D5).Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 2 Published by T. S. Wong (http://www.wong-sir.com)
  • 3. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Contents of a Cell A cell can be empty, or contain a numeric value, an alphabetic label, or a formula representing a relationship between numbers or formulae in other cells. Labels Values Empty Cells Formulae Values Values are numbers being used for calculations (e.g., raw scores obtained by students in different subjects). Labels Labels are headings used to identify the information in a spreadsheet (e.g., names of students, subject names, total scores, rankings, and so on). Formulae Formulae are step-by-step procedures that perform calculations on the values or other formulae. For examples: Total = Chin + Eng + Maths Average = Total ÷ 3Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 3 Published by T. S. Wong (http://www.wong-sir.com)
  • 4. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Formulae & Functions Formulae We use formulae to perform calculations. For example, the cell E2 that displays 218 may actually contain the formula: =B2+C3+D2 (i.e., 58 + 79 + 81) Similarly, the cell F2 that display 72.67 may actually contain the formula: =E2/3 (i.e., 218 ÷ 3) Remarks: Spreadsheet programs usually use “/” for division and “*” for multiplication. Functions Functions are formulae built into the spreadsheet programs that perform common calculations. For example, we may use the SUM function to perform the calculation so that the cell E2 may contain the formula: =SUM(B2:D2) Similarly, we can also use the AVERAGE function in cell F2 so that the cell may contain the formula: =AVERAGE(B2:D2)Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 4 Published by T.

  • 5. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Automatic Recalculation If the content of any cell changes in an electronic spreadsheet, the program will automatically recalculate the new results. There is no need to redo all the calculations just as using a manual spreadsheet. If the Maths score of Peter changes (from 81 to 71), both his Total and Average scores are recalculated automatically. What-If Analysis You can use what-if-analyses to see the effect of changing data in a worksheet. For example, what-if Simon got 60 marks in Eng, how will that affect his Total and Average scores? What-if analyses let you look into the future.Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 5 Published by T. S. Wong (http://www.wong-sir.com)
  • 6. Learning Microsoft Office For Windows — T. S. Wong ☺Introduction Word Excel Access PowerPoint FrontPage SS Basics SS Exercises Spreadsheet Basics Sorting Data Data can be sorted into specific orders in a spreadsheet program easily. Data sorted into ascending order according to the Total. Data sorted into descending order according to the Total. Formatting Data Data can be formatted in a spreadsheet just as in a word processor. Formatting Numbers Normal 10000.00 Although spreadsheet programs usually include a variety of number formats. The Comma 10,000.00 format defines only how a number looks on Currency $10,000.00 the screen, it does not affect the number Percentage 10000.00% itself.

Spreadsheet programs usually offer many types of charts for you to choose from. A legend explains the symbols or colors used in a chart.Form 4 & 5 Information Technology Microsoft Excel — Spreadsheet Basics Page 7 Published by T. S. Wong (http://www.wong-sir.com)
