Learning Outcomes:-

Through this module, you will gain understanding on:-

·         Graphic Determination of MEDIAN

(A)  less than OR more than Ogives Approach

(B)  less than AND more than Ogives Approach

Graphic Determination of MEDIAN -

 

Median value of a series may also be determined through graphic presentation of data in the form of ogives (also known as Cumulative Frequency Curve: less than/more than Ogive)

 

Frequency Curve: steps for drawing, Ogive or Cumulative Frequency Curve: less than/more than Ogive https://www.youtube.com/watch?v=M8adZhWFmS8

 

This may be done in 2 ways -

 

1.    Presenting data graphically in the form of less than OR more than Ogives

2.    Simultaneously Presenting data graphically in the form of less than AND more than Ogives i.e. The two Ogives are superimposed upon each other to determine the median value

 

1.    less than OR more than Ogives Approach -

 

Steps:-

1.    Frequency distribution series: first converted into less than OR more than Cumulative Series

2.    Data are presented graphically to make an Ogive

3.    Find out N/2 th Item and mark it on Y-Axis (vertically)

4.    From this Point on Y-Axis, a Perpendicular is drawn to the right to cut the cumulative frequency curve at Point E

 

Perpendicular = at an angle of 90° to another line or surface

5.    From Point E, where cumulative frequency curve is cut, draw a Perpendicular to X-Axis

6.    The point at which it touches X-axis will be the median value of the series

2.    less than AND more than Ogives Approach -

 

Simultaneously Presenting data graphically in the form of less than AND more than Ogives i.e. The two Ogives are superimposed upon each other to determine the median value

 

Steps:-

1.    Mark Point E where  both Ogive Curves CUT each other

2.    From Point E, draw a Perpendicular to the X-Axis (horizontally placed)

3.    Corresponding value on the X-axis would be the median value.
