There are a couple of other statistical data representation graphs but the above are the most common and the most used. Though there are no bigger differences because of the usability.

The class width is the difference between the upper or lower class limits of consecutive classes. All classes should have the same class width.
In this case, class width equals to the difference between the lower limits of the first two classes. Simplify to find that the class width is 3. The curved shape of a bullet called the ogive is more consistent than the actual tip on most bullets. Therefore, you can verify the Overall length OAL of your handloads more accurately by measuring back from the ogive to the base. An ogive oh-jive , sometimes called a cumulative frequency polygon, is a type of frequency polygon that shows cumulative frequencies.
In other words, the cumulative percents are added on the graph from left to right. An ogive graph plots cumulative frequency on the y-axis and class boundaries along the x-axis. A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon , is called an ogive.
Cumulative frequency is the running total of the frequencies. On a graph , it can be represented by a cumulative frequency polygon, where straight lines join up the points, or a cumulative frequency curve. It has a title, an x-axis, a y-axis, and vertical bars to visually represent the data.
Frequency histograms help organize data and make it easier to understand. A frequency polygon is very similar to a histogram. In fact, they are almost identical except that frequency polygons can be used to compare sets of data or to display a cumulative frequency distribution.
In addition, histograms tend to be rectangles while a frequency polygon resembles a line graph. The class midpoint or class mark is a specific point in the center of the bins categories in a frequency distribution table; It's also the center of a bar in a histogram. It is defined as the average of the upper and lower class limits. It helps to visualize the distribution of the data. Demerits are:1 Cannot read exact values because data is grouped into categories.
A frequency - curve is a smooth curve for which the total area is taken to be unity. The frequency - curve for a distribution can be obtained by drawing a smooth and free hand curve through the mid-points of the upper sides of the rectangles forming the histogram. What is the difference between ogive and frequency polygon? Category: science geography. 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. What is a disadvantage of using a stem and leaf plot instead of a histogram?
What are class boundaries? Definition: Class Boundary. What is the difference between frequency and relative frequency?
What are some benefits of using graphs of frequency distribution?
