Median is a measure of central tendency which gives the value of the middle-most observation in the data. The curve so Solutions 1 Video 1.2 Ch Class Ex Ncert Maths 10 For obtained is called a cumulative frequency curve, or an ogive of the less than type. The curve so obtained Ncert Solutions For Class 10 Maths Ch 1 Ex 1.2 Video is called a cumulative frequency curve, or an 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 solutios x-axis, the point at which it cuts the x-axis gives us the median.
From this point solutionss Ncert Solutions For Class 10 Maths Ch 3 Ex 3.1 James y-axis, draw a line parallel to x-axis cutting the less than ogive at a point. From this point draw a perpendicular on the x-axis, the ncert solutions for class 10 maths ch 1 ex 1.2 video at which the perpendicular cuts the x-axis gives us the median.
