Spreadsheet Functions


Functions

  • Simple functions

  • Array functions

  • IF - logical functions


Function notation

  • A function is a piece of computation that takes 1 or more arguments (data) and returns a value

  • Function( arg1, arg2, arg3 )

    • Sine(90)

    • Max(100,200,120,-7)

    • Sqrt( min(7+4, 9) )

Other array functions

  • Min

  • Max

  • Stdev - standard deviation

  • Median

  • Product - multiply them all together


Functions

  • Simple functions

  • Array functions

  • IF - logical functions


If

  • If ( test, trueVal, falseVal)


AND


IF with AND


Review

  • Functions - name with arguments

    • Finding functions

  • Array functions

    • Sum(B6:D32)

    • Average(F14:R75)

  • IF - AND - OR
