Frequency Histogram And Polygon. A histogram is a graph that uses the height of a column to show the frequency of each score. A frequency polygon is similar to a histogram except that the x-axis plots the mid-point for each interval. Histograms are typically used for large continuous quantitative data sets. A frequency polygon can also be used when graphing large data sets with data points that repeat.
It is formed by joining all the mid points of the tops of all rectangles however they can be formed even without constructing a histogram. Frequency polygons can be drawn in two ways. The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. Suitable scales are to be chosen for both x and y axes so that the entire data can be presented in the graph sheet. Graphical representation Histogram Frequency polygon and Frequency curve Graphs Graphs are charts consisting of points lines and curves. A frequency polygon is similar to a histogram except that the x-axis plots the mid-point for each interval.
