The most common graph shapes that occur are: Right and Left Skewing - where the data has a. In summary, the shape of a distribution is determined by the combination of its central tendency, variability, and skewness. Try and match the shape of your graph to one of the examples above. As it has essential importance because it could affect the statistical methods you are going to employ later.

You can also download this list as a printable PDF below. Whenever working with any data don’t forget to observe shape of a distribution. Here is a list of shapes in English, including both 2D shapes and 3D shapes.
Middle one has the shape of a bell curve, has one peak, and is approximately symmetric. Observe the above histogram and see the distribution. This touching represents that the values of an interval/ratio variable represent an underlying continuous scale. That difference is that the bars in a histogram touch each other. Each of these graph types has different uses depending on the kind of data that is being evaluated. However, there is one important difference. There are 3 main types of line graphs in statistics namely, a simple line graph, a multiple line graph, and a compound line graph. Histogram:Ī histogram is similar to a bar graph in the sense that it uses bars to portray the frequencies or relative frequencies of the possible values of a variable. Some of the finite structures considered in graph theory have names, sometimes inspired by the graphs topology, and sometimes after their discoverer. 
So, another kind of representation called Histogram might be useful for that case.
