What is the Difference between bar graph and histogram?
- A bar graph is a visual presentation that compares values whereas a histogram is a more specific way of presenting facts and information.
- The bars in a bar graph are placed separate from one another.
- The bars of a histogram are usually placed together, each touching the other.
- A bar graph presents the viewer with a visual presentation of discrete elements whereas a histogram presents the viewer with the frequency of non-discrete, continuous elements.
Bar graph vs histogram:
Charts and graphs help facts and information to be presented in clear and lucid forms when it comes to presentations and such matters where the information gathered need to be presented in comprehensible and concise manners. These charts not only make it easy for the audience to understand the situation clearly, they also aid them notice certain patterns and trends which would have been quite difficult to spot if the data had been presented in any other form. Bar graph and histogram are two such types of charts among many other which have made it easier for certain facts to be presented in a comprehensive manner. These two charts seem awfully similar at a first glance and yet, they do possess certain differences which in turn make them ideal candidates to present certain types of facts as opposed to others.
The difference between a bar graph and a histogram is not very easy to detect because of the apparent similarities of their physical forms. And yet, a difference that can be spotted at a first glance would be the fact that while the columns of a bar graph are set far apart, separating each bar from the other, the bars of a histogram are often placed close together, to indicate that the items presented are non-discrete, unlike the information shown in a bar graph.
A histogram is indeed a type of a bar graph and yet, it is a more specific type of a bar graph that presents values or frequencies. It represents numbers unlike that of a bar graph. A histogram is designed to present values of recorded data elements that are grouped or categorized unlike a bar graph which shows a comparison of values by helping the organization of data and information. Thus a bar graph presents the viewer with a visual presentation of discrete elements whereas a histogram presents the viewer with the frequency of non-discrete, continuous elements.
