HISTOGRAM, USES AND HOW TO CONSTRUCT IT

HISTOGRAM, Meaning of histogram

 Histogram is a graphical representation of frequency distribution. It is made up of a set of rectangles that have their bases on the horizontal axis, i.e. X – axis, and their frequency on the vertical axis, Y – axis. They also have their rectangles at the centre on the class mark (i.e mid point) of each interval.

HOW TO DRAW A HISTOGRAM

 The areas of the rectangles are proportional to the class frequencies. In drawing a histogram, there is no gap or space between two bars, unlike the bar chart.
