27. 27 Excel Spreadsheet  Spreadsheet: computer equivalent of a paper ledger sheet  Its elements: Rows, Columns, Cells  Type of data: Labels, Constants, and Formulas  Basic math functions in formulas: add, subtract, multiply, divide  Special math functions in formulas: SUM, AVERAGE, MAX, MIN, COUNT, COUNTA, IF, PMT, SIN (COS, TAN, etc)

28. 28 Excel Formulas AB 1£2.55£0.4 210005000  Example: SUM, AVERAGE Example of SUM, DIVIDECalculatesAnswer =SUM(A2,B2) (1000+5000)6000 =AVERAGE(A2,B2)(1000+5000)/23000

29. 29 Excel Formulas AB 1£2.55£0.4 210005000  Example: IF Example of IFComparesAnswer =IF(A1>1,”yes”, “no”)is (2.55>1)yes =IF(B2>8000,0.8,0.2)is (5000>8000)0.2

30. 30 Create and edit an Excel file  Using the similar method to create a new Excel file, and save it as “studentmarkbook”, and then entre the following items to this file:

31. 31 Using Excel to do calculations  You can calculate the means, variance, maximum, minimum of the marks at the column C and column D. First, selecting the column, for example, the column C in the following figure, and then click to pull out the operator of “Sum”, “Average”, etc.  Choose, for example, “Average”, you will get average listed after the third mark 66 shown as:  Similarly, you can get the summation by choosing “Sum”. Likewise, these operations can be applied to column D as well.

32. 32 Using Excel to draw a chart  We can visualise the marks in column C in the figure on the previous slide. To do this, we should first select the data, then click the following icon shown on the toolbar.  We will then see the following box
