Mode = 3 median — 2 mean, , Location of median by graph:, , (i) By ‘Less than’ or ‘More than’ ogives, method a frequency distribution series is, first converted into a less than or more, than cumulative series as in the case of, ogives, data are presented graphically to, make a ‘less than’ or ‘more than’ ogive, N/2, item of the series is determined and from, this point (on the y-axis of the graph) a, perpendicular is drawn to the right to cut, the cumulative frequency curve. The, median value is the one where cumulative, frequency curve cuts corresponding to xaxis., , (ii) Less than and more than ogive curve, method present the data graphically in the, form of ‘less than’ and ‘more than’ ogives, simultaneously. The two ogives are, superimposed upon each other to, determine the median value. Mark the, point where the ogive curve cut each, other, draw a perpendicular from that, point on x-axis, the corresponding value, on the x-axis would be the median value.
