Solution


Q.

The median of a given frequency distribution is found graphically with the help of:
1 Frequency curve  
2 Bar graph
 
3 Histogram  
4 An ogive  

Ans.

(4)

An ogive is a plot of the cumulative frequencies of a frequency distribution.
When the cumulative frequencies of class-intervals are plotted against upper or lower limits of class intervals, the graph obtained by joining the points by free hand forming smooth curve is called the cumulative frequency curve or ogive.
Ogive graphs are used to find the median of the given set of data.
