Question
The abscissa of the point of intersection of less than type and of the more than types cumulative frequency curves of a grouped data gives its ______.
Options
Mean
Median
Mode
All of the above
Solution
The abscissa of the point of intersection of less than type and of the more than types cumulative frequency curves of a grouped data gives its median.
Explanation:-
The less than ogive and more than ogive when drawn on the same graph intersect at a point. From this point, if we draw a perpendicular on the x-axis, the point at which it cuts the x-axis gives us the median.
Thus, the abscissa of the point of intersection of less than type and of the more than type cumulative curves of a grouped data gives its median.
