Why does including either endpoint not change a class width?
A
3510=3.5\frac{35}{10}=3.51035=3.5
B
For a histogram bar, frequency=class width×frequency density\boxed{\text{frequency}=\text{class width}\times\text{frequency density}}frequency=class width×frequency density.
C
Unequal widths mean a shorter bar may have a greater area.
D
Width depends only on the difference between the class boundaries.
