First calculate cumulative frequency I. E.
5+9+16+22+26+18+11+6+4+3=120 n is even so median is 120/2= 60th term then in the ogive you draw a point from 60 and where it touches the ogive bring it down to the value and calculate it... For scorers more than 75 draw a line from the 75 on x axis where it touches ogive take it to Y axis and where it touches subtract it from highest value
