A histogram is a graph that plots frequency distribution in your Excel dashboards and reports. A frequency distribution shows how often an event or category of data occurs. With a histogram, you can visually see the general distribution of a certain attribute. A nice feature to add to your histograms is a cumulative percent series.

Is a distribution that shows the number of data values less than or equal to a specific value. Histogram, Frequency Polygon, and cumulative frequency The data in frequency distribution can be presented in a graphical form such as: - The number of employees accumulated less than 3,000 miles.We have to convert the frequency distribution to a cumulative distribution.We have to draw a cumulative frequency polygon.Based on the cumulative frequency polygon, we have to find about 75 percent of the employee's accumulated how many miles or less.
The total frequency of all classes less than the upper class boundary of a given class is called the cumulative frequency of that class. A table showing the cumulative frequencies is called a cumulative frequency distribution. There are two types of cumulative frequency distributions. - Ogives do look similar to frequency polygons, which we saw earlier. The most important difference between them is that an ogive is a plot of cumulative values, whereas a frequency polygon is a plot of the values themselves. So, to get from a frequency polygon to an ogive, we would add up the counts as we move from left to right in the graph.
Here, the points are joined by using a foot rule to obtain the frequency polygon curve. Less than ogive curves: In this method, frequencies are cumulated and presented in a graph corresponding to upper limits of the classes in a frequency distribution. Firstly, all the data are converted into less than cumulative frequency distribution as follows- - Overlapping relative cumulative frequency polygons may also give additional information about how two distributions are similar or different. In many ways the overlapping cumulative frequency polygons are easier to interpret because the lines do not jump up and down as much as in the non-cumulative polygons.

Plot the points (x,y) using upper limits (x) and their corresponding Cumulative frequency (y) Join the points by a smooth freehand curve. - Ogives are known also as cumulative frequency curves and there are two kinds of ogives. One is less than ogive and the other is more than ogive. Less than ogive: Here the cumulative frequencies are plotted against the upper boundary of respective class interval. Greater than ogive: Here the cumulative frequencies are plotted against the lower
