    - Bar diagram, frequency histogram, Pi diagram, frequency bar chart, frequency polygon are the different diagrams used to represent data.

    Frequency histograms:

    - In frequency histogram, X axis represents cell interval and Y axis represents frequency.
    - Cell frequency is proportional to height of the rectangles in the histogram.
    - Two rectangles can be drawn side by side by different colors.

    Frequency bar chart:

    - In this chart, frequency distribution data is represented by bars. The bars are centered at the midpoint of the cell.

    Bar diagram:

    - In this diagram, the bars are separated from each other at equal intervals.
    - Each bar is represented by a detail below to which it corresponds.
