Frequency Polygon And Histogram. So to get from a frequency polygon to an ogive we would add up the counts as we move from. It is also used to represent the distribution of data graphically. From Histograms to Frequency Polygons. Histograms with frequency polygons are often used in statistics to organise quantitative data and visualise frequency distributions.
The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. Histogram and frequency polygon are very useful graphics to have an idea about the distribution of a continuous variable. A frequency polygon can also be used when graphing large data sets with data points that repeat. Histograms are typically used for large continuous quantitative data sets. A frequency polygon is almost identical to a histogram which is used to compare sets of data or to display a cumulative frequency distribution. 23 Measures of the Location of the Data.
The heights of the bars correspond to frequency values.
27 Measures of the Spread of the Data. The frequency polygon is a graph that displays the data by using lines that connect points plotted for the frequencies at the midpoints of the classes.

Histogram and frequency polygon are very useful graphics to have an idea about the distribution of a continuous variable. 23 Measures of the Location of the Data. The histogram is a graph that displays the data by using contiguous vertical bars unless the frequency of a class is 0 of various heights to represent the frequencies of the classes.
