3
Understand how to use a range of different functions in excel. Used a range of functions within your excel spreadsheet.

4
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

5
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

6
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

7
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

8
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

9
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

10
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

11
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

12
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

13
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

14
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.

15
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.
