Fill in the blanks.
In 'Less Than' Ogive, the cumulative frequencies are written corresponding to the __P__ limits of the classes of the given data.
In 'More Than' Ogive, the cumulative frequencies are written corresponding to the __Q__ limit of the classes.
On an ogive, point P whose y - coordinate = n/2 (i.e., half of the total number of the entries), has its x - coordinate equal to the __R__ of the data. Two ogives, one 'less than' type and the other 'more than' type for the same data when drawn simultaneously on the same graph, intersect each other at the point P whose __S__ = n/2 and __T__ = median of the data where n is the total number of the entries of the data.

CUpper - Lower - Median x - coordinatey - coordinate
DUpper - Lower - Upper limity - coordinatex - coordinate
