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
