Without drawing the histogram we can draw the frequency polygon.for drawing this type of graph we need the midpoints and formula for finding the midpoints for each class is as follows, Class mark $$=$$ Midpoint $$=$$ Upper limit $$+$$ Lower $$limit2So$$ the midpoint table for both sections is and the frequency polygon is ,
