Aaron's Graphing Post

1. Types Of Graphs:

1. Bar Graph:Advantage: You can easily compare two or three data sets.
Disadvantage: Not that good for a big number of categories.

2. Double Bar Graph:Advantage: You can easily compare two sets of data across categories.
Disadvantage: Can only compare two sets of data.

3. Circle Graph:Advantage: You can easily compare categories to a whole using percents.
Disadvantage: Its only good for 3-7 categories and its hard to compare two data sets.
icto graph is easy to read and it handles large data sets easily using icons.
The icons must be the same size and its only best for 2-6 categories.

5. Line Graph:Advantage: Can compare more than one types of data sets easily.
Disadvantage: Its only good for data that keeps going.

6. How can graphs be misleading?
1. Putting a break in the y axis.
2. Making one bar 3D
3. Coloring one bar.

7. The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?
1. Bar Graph
2.Line Graph

8. If you were selling Pizza Subs would you continue? How does your graph explain your answer.

1. Yes because my graph tells me i'm selling more every week.

9. 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?

1. I would choose the line graph because it shows that the sales go up every month.

10. Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.
