Draw a frequency polygon for the following frequency distribution.
We take the imagined classes (-9, 0) at the beginning and (61-70) at the end, each of the frequency 0.
Thus we have,
We plot the following points on the graph,
A (-4.5, 0)
B (5.5, 8)
C (15.5, 3)
D (25.5, 6)
E (35.5, 12)
F (45.5, 2)
G (55.5, 7)
H (65.5, 0)
Now we draw the line segment AB, BC, CD, DE, EF, FG, GH, to obtain the frequency polygon.
