median marks obtained by the students of the class
• From graph No. of students are 40
• n=40 & n/2=20
• In an cumulative frequency graph
or an ogive for finding median we
have to look for the corresponding
value to the n/2
• In this case n/2 =20 & corresponding marks to n/2 are 50
• Hence median is 50 marks
