pICTOGRAPHS
Graph that uses pictures to show quantities. A pictograph might be used to represent the number of people that like certain types of pizza. The pictograph below contains pictures of pizza and the key beneath the pictograph tells us that each picture of a pizza liked.
We can then calculate the total pizza liked by people as follows;
Cheese : 5 x 5 = 25 people like cheese
Mushroom : 4 x 5 = 20 people like mushroom
Sausage : 5 x 5 = 25 people like sausage
Pepperoni : 6 x 5 =30 people like pepperoni
