Taylors Graphing Post

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph.

-Bar graphs:
Advantage-Are best for comparing data across categories.
Disadvantage-Graph categories can be reordered to emphasize certain effects.

-Double bar graphs:
Advantage-Are best for comparing two sets of data across
Disadvantage-Graph categories can be reordered
to emphasize certain effects.

-Circle graphs:
Advantage- Are best for comparing to the whole using percents. The sum of the percents in a circle graph is 100%.
Disadvantage- Its hard to compare 2 sets of data.

-Line graphs:
Advantage- Are best for showing data over time
Disadvantage- It isn't as visually appearing as the other ones.

-Pictographs:

Advantage- Are best for comparing data that can be easily counted and represented using symbols.
Disadvantage- Icons must be the same sizes or el
se it will be distorted.

2. How can graphs be misleading. Show 3 ways.
Distorting the sizes
Colouring it in
Make it 3D

2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?
Pictograph and Line-graph
2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.
Yes I would continue selling them because every week it the number of Pizza Subs sold goes up.

4. 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 show Mrs.Mota the line graph because you can really see how much it went up each month.

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.
You can add different colours, use different images and make lines thicker.
