Expert Answer:

begin mathsize 12px style The space less space than space type space ogive space is space obtained space by space marking space the space upper space limits space on space the space straight x minus axis space and space the space corresponding space cumulative space frequencies space on space the
straight y minus axis. space The space more space than space type space ogive space is space obtained space by space marking space the space lowerr space limits space on space the space straight x minus axis space and space the space corresponding space cumulative space frequencies space on space the
straight y minus axis.
While space plotting space each space graph space separately comma space locate space straight n over 2 space on space the space straight x minus axis comma space form space this space point space draw space straight a space line space parallel space to space the space straight x minus axis space cutting space the space curve space at space straight a space point.
From space this space point comma space straight a space perpendicular space to space the space straight x minus axis space is space drawn space to space obtain space the space median space on space the space straight x minus axis.
For space both space the space graphs comma space after space drawing space the space curve comma space the space process space is space same. space So comma space if space the space graphs space are space drawn space together space on space the space same space graph comma
their space are space bound space to space intersect space at space the space same space point. end style
