UGC NET COMMERCE December 2018 Q8
- Option : A
- Explanation : Graphical method of locating the median
Median can be located with the help of a cumulative frequency curve or by an ‘ogive’ curves. From the point of intersection of ‘less than’ and ‘more than’ ogives, if a perpendicular is drawn on the X axis, the point so obtained on the horizontal axis gives the value of the median.
If ogive is drawn using cumulated percentage frequencies, then we draw a straight line from the point representing 50 percent cumulated frequency on the Y-axis parallel to the X-axis to intersect the ogive. A perpendicular drawn from this point of intersection on the horizontal axis gives the value of the median.
