Consider the following statements about ogive: 1. It is a graph of cumulative frequency. 2. The median can be located from the point where cumulative frequency is N/2. 3. Ogive can be used to estimate mode. Which of the above is/are correct?
A. 1, 2 and 3
B. 2 and 3 only
C. 1 and 3 only
D. 1 and 2 only
Answer: Option D
