Histogram
Histogram is a graphical representation of a grouped frequency distribution in exclusive form with continuous classes in the form of rectangles with class intervals as bases and the corresponding frequencies as Heights.
There is no gap between any two consecutive rectangles.
In histogram we draw a kink.
Kink i.e. break is indicated near the origin to signify that a graph is drawn not at the origin.
If the first class interval is not starting from zero , then we show it on the graph by making a kink or a break on the axis.
