5
IF loving you is wrong THEN I dont want to be right

6
IF-THEN Statements If, Then, Else (a.k.a. Otherwise) What is your procedure? In excel this is written as : IF(Condition, True Value, False Value)

7

8
Sample Problem 1 Yes Speed > 65 No Issue Ticket No Ticket

9
Sample Problem 1 Speed Caught TravelingAction To Be Taken 65Issue Ticket 55No Ticket Speed Caught TravelingAction To Be Taken 65=IF(A11<65,"No Ticket","Issue Ticket") 55=IF(A12<65,"No Ticket","Issue Ticket")

10
Nested IF-THEN Statements What if you have a second condition? IF(Cond, True,IF(Cond, True, False))

11
Sample Problem 2 If a driver is going over 65 mph or under 45 mph a speeding ticket should be issued.

12
Sample Problem 2 Yes Speed < 40 No Issue Ticket Speed > 65 YesNo Issue TicketNo Ticket
