Spreadsheet 5 Function
Objectives • Use functions like Sum and Average • Use a shortcut to compute the total for columns and rows
3.1 Introduction • Spreadsheet allows you to enter formulae to perform calculations efficiently • A ‘function’ is a built-in formula that comes with a spreadsheet program • It is used in place of a long formula
3.1 Introduction • The Sum function • In cell B10, instead of using the long formula “=B3+B4+B5+B6+B7+B8+B9” to add up cells B3 to B9, a function “=SUM(B3:B9)” is used The range B3:B9 indicates the cells to be summed up
3.1 Introduction • The Average function • In cell B8, instead of using the formula “=(B4+B5+B6)/3” to average up cells B4 to B6, a function “=AVERAGE(B4:B6)” is used
3.1 Introduction • The Maximum and Minimum function • The Maximum function returns the maximum value from a range of cells specified • The maximum value in cells B4 to B10 is 60 and the Maximum function will find it
3.1 Introduction • The Maximum and Minimum function (Cont’d) • The Minimum function returns the minimum value from a range of cells specified • The minimum value in cells B4 to B10 is 29 and the Minimum function will return this value
3.2 Copying Cell Contents • You can copy cells by click-and-drag
3.2 Copying Cell Contents • To copy using click-and-drag • Move the cursor pointer to the bottom-right corner of the cell to be copied • When the mouse pointer changes to a plus sign, right click and drag to select the range that you want to copy to • Release the mouse button at the end • The cell content will be copied to the selected range
3.2 Copying Cell Contents • = SUM(B1:B3) or = B1 + B2 + B3 • = SUM(C1:C3) or = C1 + C2 + C3
Summary • A function is a built-in formula that comes with a spreadsheet program. It is used in place of long formulae. • The Sum function is used to find the total of the values in a range. • The Average function is used to find the average of the values in a range.
Summary • We can use the click and drag method to copy cell contents.
