What is the relationship between class width and frequency density in a histogram?
Frequency density is always greater than class width.
The larger the class width, the smaller the frequency density.
They are inversely proportional.
They are directly proportional.
Explanation
When class widths are unequal, frequency density must be considered to not misrepresent the data.
