  • The abscissa of the point of intersection of the less than type and of the more than type cumulative frequency curves of a grouped data gives its (A) mean(B) median (C) mode(D) all the three above

The abscissa of the point of intersection of the less-than-type and of the more-than-type cumulative frequency curves of grouped data gives its
(A) mean; (B) median; (C) mode; (D) all three above

Answer. [B]
Solution. Frequency distribution: It tells how frequencies are distributed over values in a frequency distribution. However, we mostly use frequency distribution to summarise categorical variables. 
If we make graph of less-than-type and of more-than-type grouped data and find the intersection point, then the value at abscissa is the median of the grouped data.
Hence, option (B) is correct.
