Aicelle's Graphing Post

There are 5 different graphs that can be represented.
Graphs: Bar Graphs, Line Graphs, Double Bar Graphs, Circle Graphs, and Pictographs.


Bar Graphs
















Advantage - Good for comparing across categories.
Disadvantage - You can only use it with several data.

Line Graphs

Advantage - Good for showing changes over time.
Disadvantage - You can only use it when it changes over time.

Double Bar Graphs
















Advantage - Good for comparing 2 sets of data across categories.
Disadvantage - You might get mixed up.

Circle Graphs
















Advantage - Good for comparing to the whole using percents.
Disadvantage - You will not know the exact number and it also takes long to do.

Pictographs
















Advantage - Good for comparing data that can be counted easily.
Disadvantage - You will not know if it is a half or not.

3 ways you can misrepresent a graph.

Break in the y-axis.
















Make one picture bigger than the other.
















Colour one bar different from the others.
















The 2 graphs that will show it more accurately are line graphs and a bar graph.




























If I was selling Pizza Subs I will continue because a lot of people are buying every week.

I would choose a Line Graph because it shows that every month, a lot more people are choosing healthy food.
