The histogram is closest to the bar graph. If the bars in a graph drawn are touching

frequency distribution is given. The steps of drawing a histogram are the same as
that of the bar chart. The idea needs to be taught with the provision of an embossed
chart depicting the construction of an histogram for some data.
