Might as well give the full lesson:
Conditional statements: you imply that your conclusion is judged by your hypothesis
Converse statements: you imply that your hypothesis is judged by your conclusion
Inverse statements: your hypothesis is now opposite, therefore your conclusion is now opposite
Contrapositive statements: your conclusion is now opposite, therefore your hypothesis is now opposite
Biconditional statements: your conditional and converse statements are both true.
EDIT: Example:
"You don't like hockey if you don't go to the hockey game"
Conditional: If you don't like hockey, then you don't go to the hockey game
Converse: If you don't go to the hockey game, you don't like hockey.
Inverse: If you like hockey, then you go to the hockey game.
Contrapositive: If you go to the hockey game, then you must like hockey
