The point of intersection of more than and less than type ogive is (25,30)the total number of frequencies is ? |

Answer» Answer: point of intersection of less than more than type ogives of a GROUP data is (27, 12) . means, the type of CUMULATIVE frequency CURVES, less than or more than ogives , meet at point (27, 12) . Thus, median = x co-ordinate of the point of intersection of more than ogive and less than ogive . here x co-ordinate of the point of the intersection of more than ogive and less than ogive is 27 . so,total frequency of DATE = median = 27. hence, answer is 27. |
