Now she observes that since the largest number of students of her class  
like football, this means – ‘ Football is the favourite and the most popular  
sport’.
Anwesha can represent this data in the form of PICTOGRAPH, BAR 
GRAPH and CHAPATI CHART.
Tutty Speaks
         In Pictographs , we use pictures or symbols 
       to convey how many times a data occurs.
 In Bar graphs , we use rectangular bars. The lengths  
of bars convey the value of a data.
In Chapati Charts , a circle is divided into parts to  
show and compare information.
