Such a table is called grouped data. The class with the maximum frequency is called modal class. Median is a measure of central Class 8 Maths Ch 10 Ex 10.1 Student tendency which gives the value of claxs middle-most observation in the data. The curve so obtained is called a cumulative frequency curve, or an ogive cg the less than type. The cide so obtained is called a cumulative frequency curve, or mathw ogive of the more than type.
The two ogives will intersect each other 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. From this point on y-axis, draw a line parallel to x-axis cutting cn less than ogive at a point.
