*Bargraph*

*Disadvantage: The exact amounts aren't clear depending on the scale*

*Pictograph*

*Advantage: It's best for data that can be easily counted*

*Disadvantage: You can only use pictograph if the data is even*

*Circle Graph*

*Advantage: Best for comparing categories to whole using percent*

*Disadvantage: You have to multiply to determine the number*

*How a graph can be misleading?*

*1: Break in the y axis*

*2: Making one bar larger*

*3.a What two graphs would you use?*

Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs. Mota that we should continue selling healthy choices which graph would you choose?

I would choose the line graph because it shows Mrs.Mota that it goes higher and higher over time. If you choose the pictograph you have too count and count until you find the exact amount.

4a).

Change the graph, to make it look more impresive. you may not change the data.
