'More than Ogive' is a falling curve.
To Find Median from both Cumulative Frequency Curve(Less than
type & More than type)
Example -1: The table given below shows the frequency distribution of the scores
obtained by 200 candidates in a BBA entrance examination.
Score Number of candidates
200 - 250 30
250 - 300 15
300 - 350 45
350 - 400 20
400 - 450 25
450 - 500 40
500 - 550 10
550 - 600 15
Draw cumulative frequency curves by using
(i) 'less than' type
(ii) 'More than' type
Hence, find the median
