When the class intervals have equal widths, how does the height of a bar in a histogram relate to the frequency?
The height is directly proportional to the frequency.
The height is inversely proportional to the frequency.
The height is equal to the frequency density.
The height is unrelated to the frequency.
Erläuterung
When the widths are consistent, a bar's height directly reflects the frequency.
