Spreadsheet I n Concepts & operations

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

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

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

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

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

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

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

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

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

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

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

XY/Scatter chart n for plotting mathematical functions

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
