Valid vs Strong

As similar valid arguments and strong arguments sound, they are two different concepts. A valid argument can be strong, and a strong argument can be valid. But a strong argument can also be invalid. A strong argument provides premises that are true but a conclusion that is false. A valid argument provides an argument that cannot be false. Basically a valid argument does not need a strong premise to be true. For example you could say that studying for exam will increase your chances of receiving an A and it would be valid. But to make it stronger, you would include that studying the class notes and what follows closely would also aid in the accuracy of what will exactly be on the test. For strong arguments you could make a good argument about why abortions should be allowed, but it doesn't necessarily need to be valid. It could sway people, but it wouldn't cause everyone to change their decisions.
