Remember: A frequency polygon is a line graph that isdrawn by joining points given by the class mid-points and classfrequencies. So, the original frequency distribution can be reconstructed from the frequency polygon. Hence, statement 1 is correct Remember: The frequency polygon touches the x-axis at its extreme right and extreme left. These correspond to the midpoints of two class intervals of zero frequency on the x-axis, one adjacent to the first on its left and one adjacent to the last on its right.
