How to make a frequency polygon
Frequency polygon graphs can be building up from histograms by combining the midpoints of the histogram bars with the outline. The spaces below the frequency polygon graph and histogram chart are identical. Frequency polygon graphs show as a graphic representation of a frequency distribution build up by plotting all frequency above the score or mid spot of a class interval laid out on a base line and linking the points that plotted by a straight line. Explanation of Frequency Polygon Graph: Frequency polygon graphs show like as histogram chart where the regulations applicable for histograms are also applicable for frequency polygon graph. They are a smoother substitute to histograms. A frequency polygon graphs is a graphical present of a frequency table. The time or other intervals are show on the X-axis and the number of scores in each interval is representing by the elevation of a point located above the center of the interval. The learning of points is involving so that collectively
