Bin Width:  When you make a histogram, you're essentially making a bar chart that shows how many data points fit within a certain range. That range is the bin width. For instance, suppose you were counting the number of questions that people answer on this site per hour. You might plot it as 1-5, 6-10, 11-15 and so on. In that case, your bin width would be 5 - every bar on your histogram represents a range of five questions. You could take the same data and plot it as 1-10, 11-20, 21-30 and so on. In that case, your bin width would be 10. Obviously, the larger you make your bin, the more detail you lose. The narrower the bin, the more you're sort of missing the point of a histogram. 

Deviation:  The basic question behind this topic is, “How far is a typical point from the center?” You measure how far each point is from the mean (each point’s “deviation”), take the absolute value to make sure that distance is positive, then average those numbers.
