What do each do to a video file? Does an increase or decrease in one affect quality? Size?

The bitrate is the number of bits (or any other unit if specified) used to store one second of media (video, sound etc.).
The frames/second (framerate) is the number of pictures (frames) shown on your screen in one second.

With those definitions in mind, increasing the framerate increases the smoothness of moves you see on the screen. But there is a limit: due to human eye limitation, increasing the framerate in a movie above 25 frames/second doesn't increase the smoothness any more. So this is why most videos are made using that framerate.
Now, increasing the bitrate means you can store information for a second of your media in more bits. It's like trying to say something but you are allowed to use only a certain number of words. The more words you can use, the more precise you can say what you want to. There are limitations here too: from a certain bitrate beyond, you won't see any increases in quality.
Ofcourse, the higher the framerate and bitrate, the greater the quality but the greater the file size too!

I hope that helps you.
All the best!!!

Lower bitrate and low frames per sec results in a low quality video and a small size
