Options

• Mean   

• Median

• Mode

• All of the above

Answer 1

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.
