Advantages and disadvantages of common graphs Talking about the disadvantages of line graphs over bar charts is like talking about the disadvantages of screwdrivers over spanners: they are two different tools for two different jobs, and both are useful, but for different things. The dependent variable may be discrete or continuous. skewness is a measure of asymmetry in a statistical distribution. a measure of location. Histograms allow viewers to easily compare data, and in addition, they work well with large ranges of information. It is also easier to manipulate the data in graph form to make it appear as though the data is askew or reaches a certain conclusion. One common graph type that is often used is the bar graph.
