1. Spreadsheet I n Concepts & operations

2. Concepts n Workbook: Excel file n Worksheet: sheet n Row: 1-???? n Column: A - Z, AA - ?? n Cell n Cell address e.g. A5

3. Formula n starts with = n operators: +, -, *, /, (),, =, <>, =, and, or, not n functions: average(), sum(), if(), max(), min(), left(), mid(), right()

4. Cell address (1) n relative address –update automatically when the formula is copied to another cell –the relative position of the referred cell with respect to the current cell is recorded

5. Cell address (2) n absolute address –the address will not change even if the formula is copied to another cell –the exact position of the referred cell is recorded

6. Editing worksheet n create, open, retrieve, save, save as n printing worksheet –one worksheet = one page? –page setup n Insert/delete a row/column n name a range n cut and paste, erase a range n split windows and freeze heading

7. Formatting n Column width and row height n input date, number, text, time format n border and shading

8. Data Manipulation n copy formulae n autofill n sorting –multiple keys –ascending and descending

9. Graphs n charts are more attractive than a table of data n easier to interpret data trend with a chart n bar chart, pie chart, line chart n chart components: title, labels, legend n adding graph –on the same worksheet –on a new worksheet

10. Column/bar chart n general purpose n usually used in data sets, which consist of qualitative descriptions n e.g. statistics of examination results n e.g. Sales amount in recent years

11. Pie chart n used to present data describing the composition of a whole n greater sector represents greater proportion

12. Line chart n best for presenting data set where values between two categories can be interpolated

13. XY/Scatter chart n for plotting mathematical functions

14. Spreadsheet applications n calculate final mark from several component papers n quotation n sales trend/financial report n solving equation n what-if analysis/data analysis n simple database manipulation –sorting, grouping, pivot table
