6. You should now see a histogram on your worksheet. will automatically pick the histogram chart for data arranged like this, provided that the classes are uniformly created for the data. The points plotted as part of an ogive are the upper class limit and the corresponding cumulative absolute frequency or cumulative relative frequency. We will get the Frequency Function Dialogue box as . [CDATA[ A diagram representing grouped numerical data in which cumulative frequency is plotted against upper class boundary, and the resulting points are joined by straight line segments to form a polygon. For those who are new to this term, a frequency polygon is a visual representation of data using a line graph to draw the frequency values based on their classes. See also ogive; step diagram. The tool will create the . If you take a look at your chart, you will see that you have successfully created a frequency polygon based on the test score data provided. That means the number of houses with the count of vehicles "<=2". Join these points successively by line segments, we will get a polygon, known as a cumulative frequency polygon.
