Frequency table of the marks of 50 students as given below:
Given that the median marks are 28.5, the missing frequencies will be
f1 = 5, f2 = 7
f1 = 8, f2 = 7
f1 = 7, f2 = 9
f1 = 7, f2 = 5
Marks obtained by 200 students in an examination are given below :
Draw an ogive for the given distribution taking 2cm = 10 marks on one axis & 2 cm = 20 students on the other axis. Using the graph determine:
