Differences Between Diagrams and Graphs
The following are the major distinctions between diagrams and graphs.

  • Diagrams are used only for comparison and give mostly qualitative analysis like higher or lower whereas a graph is used mainly to present qualitative data.
  • Diagrams show the approximated result whereas graphic presentation is more precise and accurate and drawn only in graph papers for accuracy.
  • The graphical presentation is done in two dimensions and they present mathematical relationships between variables, whereas diagrams might be uni-dimensional or multidimensional.
  • The diagrammatic presentation looks attractive and can be understood even by illiterate people, but a graphic presentation of data is relatively complex and can be used to further mathematical treatment.
  • Construction of graphs is easier as compared to the construction of diagrams because graphs take concrete forms but drawing diagrams is like an art.
  • The presentation of a frequency distribution is not used in diagrams, but these can be easily presented in graphic presentation.
