Question

The mode of a frequency distribution can be determined graphically from :

(A) histogram (B) frequency polygon

(C) frequency curve (D) ogive

Answer 1

The value of Mode can be graphically determined in a frequency distribution. For this the series has to be first represented by a histogram. After this two lines are drawn diagonally inside the modal class in such a way that they touch the upper corner of the modal bar and the upper corner of the adjacent bar. Then a perpendicular is drawn from the intersection of these lines to the x-axis. The point at which the perpendicular touches the x-axis gives the modal value.
