G042 Task 4

 Understand how to use a range of different functions in excel.  Used a range of functions within your excel spreadsheet.

 The syntax for sum function =Sum(first cell:last cell) ExampleCells to ADDAnswer =sum(A1:A3)A1, A2, A3150 =sum(A1+A4)A1, A4#VALUE! =sum(A1:A2, A5)A1, A2, A575

 The syntax for max function =Max(first cell:last cell)  The syntax for max function =Min(first cell:last cell) ExampleCells look atAnswer =max(A1:A5)A1, A2, A3, A4, A513 =mix(A1:A5)A1, A2, A3, A4, A575

 The syntax for average function =Average (first value, second value, etc.) ExampleCells to averageAnswer =average(A1:A4)A1, A2, A3, A462.5 =average(A1:A4, 300)A1, A2, A3, A4 and 300100 =average(A1:A5)A1, A2, A3, A4, A562.5 =average(A1:A2, A4)A1, A2, A458.3

 To work out the median =Median (first value, second value, etc.)  To work out the mode =Mode (first value, second value, etc.) ExampleCells look atAnswer =mode(A1:A5)A1, A2, A3, A4, A536 =median(A1:A5)A1, A2, A3, A4, A536

 The syntax for sum function =Count(first cell:last cell)  Blank entries are not counted.  Text entries are NOT counted. Example of CountCells to look atAnswer =Count (A1:A3)A1, A2, A33 =Count (A1, A3)A1, A3,2 =Count (A1, A4)A1, A41 =Count (A1, A5)A1, A51

 The syntax for sum function =CountA(first cell:last cell)  Blank entries are not counted.  Text entries are counted. Example of CountACells to look atAnswer =CountA (A1:A3)A1, A2, A33 =CountA (A1, A3)A1, A3,2 =CountA (A1, A4)A1, A42 =CountA (A1, A5)A1, A51

 The syntax is =IF (condition, value-if-true, value-if-false)  value returned may be either a number or text  if value returned is text, it must be in quotes Example of IF typed into Column BCells to look atAnswer =IF (A2>1,"Yes","No")is (.95 > 1)No =IF (A3>1,"Yes","No")is ( 1.37 > 1)Yes =IF (A5>10000,.08,.05)is (14000 > 10000).08 =IF (A6>10000,.08,.05)is (8453 > 10000).05

 The syntax for sum function =CountIf(first cell:last cell, criteria) Example of CountAWhat looking forAnswer =COUNTIF(A2:A5,"apples")Number of cells with apples in the first column above2 =COUNTIF(A2:A5,A4)Number of cells with peaches in the first column above1 =COUNTIF(A2:A5,A3)+COUN TIF(A2:A5,A2) Number of cells with oranges or apples in the first column above 3 =COUNTIF(B2:B5,">55")Number of cells with a value greater than 55 in the second column above 2 =COUNTIF(B2:B5,"<>"&B4)Number of cells with a value not equal to 75 in the second column above 2 =COUNTIF(B2:B5,">=32")- COUNTIF(B2:B5,">85") Number of cells with a value greater than or equal to 32 and less than or equal to 85 in the second column above 3

 Int returns the nearest integer  The syntax for Int function =Int(number) ExampleDescriptionAnswer =Int(-8.9)Rounds down-9 =Int(8.9)Rounds down8 =Int(A2)Rounds down 19.519 =A2-Int(A2)Returns the decimal0.5

 Returns a value from a list  The syntax for VLOOKUP function =VLOOKUP(lookup_value, table_array, column where return data is, false) ExampleDescriptionAnswer = VLOOKUP("DI-328", A2:D6, 3, FALSE) Returns the cost price of diapers\$21.45 = (VLOOKUP("WI-989", A2:D6, 3, FALSE) Returns the cost price of wipes\$5.12 = VLOOKUP(“BI-567", A2:D6, 3, FALSE)* (1+(VLOOKUP(“BI- 567", A2:D6, 4, FALSE))) Returns the sale price of bib by finding the cost and multiplying by the mark up \$4.98

 In excel there is a help tool for functions called the function wizard.  There are two ways to get the the function wizard. If you look at the standard toolbar, the function wizard icon look like the icon on the right.  The other way to get to the function wizard is to go to the menu INSERT -- down to FUNCTION.

 Add a range of useful functions to your spreadsheet – think why you are going to include them – don’t just include for the sake of it.
