" columns) instead of an histogram from 0 to 12 on the x axis and the frequency on the y axis. Thus far I have a histogram that looks like this: Note how this is essentially a histogram, just with space between the bars and better labels (compare with histogram class, discrete frequency). Relative Frequency Histogram A relative frequency histogram is a graph that shows the proportion or percentage of data values in each class interval instead of the exact number.
