Step 2: Add a fourth column and cumulate (add up) the frequencies in column 2, going down from top to bottom. A measure of average is a value that is typical for a set of figures. To construct a frequency polygon, first examine the data and decide on the number of intervals, or class intervals, to use on the x-axis and y-axis. Statistics deals with the collection of data and information for a particular purpose. The concept of give comes related with the concept of cumulative frequency graph. A frequency is the number of times a data value occurs. 4. Ogives do look similar to frequency polygons, which we saw earlier. I’ll start by checking the range of the number of cylinders present in the cars. To construct a frequency polygon, first examine the data and decide on the number of intervals and resulting interval size, for both the x -axis and y -axis. The most important difference between them is that an ogive is a plot of cumulative values, whereas a frequency polygon is a plot of the values themselves.
