Here are the exam grades of 15 students: 88, 48, 60, 51, 57, 85, 69, 75, 97, 72, 71, 79, 65, 63, 73 When creating a histogram, we can chose to break the data into intervals differently (for example: 45-50, 50-55, 55-60 etc. vs. 40-50, 50-60, etc.). To see how our choice of bins or intervals affects the histogram, you can use the applet below that lets you change the intervals dynamically. Try changing the bin width by dragging the point underneath the bin width scale.
