strong vs. valid arguments

In my last blog post, I mentioned that it is crucial to recognize an argument as either strong or valid, which leads me to this next question: What is the difference between a strong argument and a valid one? An argument is considered to be strong when it is probable that the conclusion may be false although the premises of the beginning approach may be true. That means that while the basis of the premise is true, the conclusion may possibly be false. A valid argument, on the other hand, is when both the premises and the conclusion have the same connection—in this case, both being true. When the beginning approach and the ending argument agree and are both true, it means that the argument is therefore considered a valid argument. Take these statements for instance: “Every time she sits in a bus, she gets dizzy. Therefore, she is car sick.” It may be true and likely that she gets lightheaded every time she rides in a bus, but that does not necessarily mean that she is car sick. Maybe she happened to be going to the mountains and going up and down hills every time she was in a bus. It is also possible that the bus has been driving on winding roads to go to her destination every single time she’s in it, but one cannot assume she is car sick simply because of the mere fact that she gets dizzy on the bus. Therefore, the above argument would be considered strong because the premises of it and the conclusion don’t match up. For example, “She needs to check her emails frequently in order to know what is going on in her classes. Therefore, she must have access to the internet in order to not fall behind in her classes.” Those statements would be considered valid because both the premises of it and its conclusions match up and are both true.
