Priya's Graphing Post

1) Bar Graph
Advantage: Best for comparing data across categories.
Disadvantage: Won't work with all numbers.

2) Pictograph
Advantage: Best for comparing data that can be easily counted and represented using symbols.
Disadvantage: Harder to use some numbers like 7, 15, 12 etc.

3) Circle Graph
Advantage: Best for comparing categories to the whole using percents.
Disadvantage: Circle Graph can take longer and is harder.

4) Double Bar Graph
Advantage: Best for comparing two sets of data across categories.
Disadvantage: The interval you use might not even work.

5) Line Graph
Advantage: Best for showing changes in data over time.
Disadvantage: You can only use the data that changes over time.


3 ways a graph can be misleading:

1) Make the bar's look wider.






2) Distort the scale.



3) Distort the visuals.


2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately? I think the two graphs that would show the information more accurately is a bar graph and line graph.

2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer. Yes I would continue, because both graphs show that the graph is getting higher.

4) If I had to convince Mrs. Mota that we should continue selling healthy choices, I would choose the line graph.
