Histogram And Frequency Polygon. They are essentially bar-line graphs the histogram is a bar graph and the frequency polygon is a line grpah but without the gaps between the bars in the bar graph. A frequency polygon can also be used when graphing large data sets with data points that repeat. Check the Frequency Polygon box to show the frequency polygon. It is easier to draw a frequency polygon after a histogram is drawn.
They are essentially bar-line graphs the histogram is a bar graph and the frequency polygon is a line grpah but without the gaps between the bars in the bar graph. The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. With a histogram ii. However it has a major difference when compared to the histogram. Histograms are typically used for large continuous quantitative data sets. Draw a frequency polygon for the data above without constructing a histogram.
Whereas a histogram is built of bins with a width representing the interval and a height representing the quantity of data points in each interval a frequency polygon is constructed by drawing a point to represent the frequency of a particular interval and connecting that point to the one representing the frequency.

It distributes the x a x i s into bins by dividing the entire range of values into nonoverlapping intervals and then counting the number of observations in each bin.
