Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.
what is the difference between a regular histogram and a percent frequency polygon
Oh, dude, it's like this: a histogram is like a bar graph that shows the frequency of data within specific intervals, while a frequency polygon is a line graph that connects the midpoints of the intervals in a histogram. So, it's like the difference between drawing bars and connecting dots. Cool, right?
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
A histogram is a type of graph
A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.

Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.
A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.
the bell curve shape? anonymous
A histogram when plotted as a bar diagram, shows the frequency or relative frequency of a set of data. An example of bar chart that is not a histograms would be a plot of the average salary of Americans from 1980 to year 2000. However, if the salaries were broken into groups, and a chart showed the number or percentage of Americans making less than $100,000 and those making more, this would be a histogram.
Frequancy Tables only use whole numbers while relative frequency tables use exact percentages or decimals.
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.
