Histogram A histogram is from of graphical representation of grouped frequency distribution with continuous classes.  In a histogram data represents like the bar graph, but it there is no gap between rectangular bars. The rectangular bars show the area of proportional to the corresponding frequency of a variable and the width of the bars represents […]
