Marielle's Graphing Post

Types of Graph

Bar Graph

Advantage- Best comparing data across categories.

Disadvantage- Can not easily figure the exact number.

Double Bar Graph
Advantage- Best comparing two sets of data across categories.

Disadvantage- can not easily figure the exact number.

Line Graph

Advantage- Best for showing changes in data over time.
Disadvantage- Not best for comparing data across categories.

Double Line Graph
Advantage- Best for comparing two sets of data across categories.
Disadvantage- Not best for comparing the data of each across categories.

Circle Graph
Advantage- Best for comparing categories to the whole using percents.

Disadvantage- Can not determine the exact number/total and have to change the number and percent

Pictograph

Advantage- Best for comparing data that can be easily counted and represented using symbols.

Disadvantage- multiply how many picture there are and how many of each picture cost.

Misleading Graph

- Distorting the scale (Breaking the y-axis)

- Distorting visual (Make an image larger)

-Distorting bar size (Make bar/s wider)



2a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately? I would use pictograph and a graph
2b) If you were selling Pizza Subs would you continue? How does your graph explain your answer
I would continue selling because every month the pizzas are being sold is getting higher and higher.

If I had to convince mrs. Mota That we should continue selling heathly food choices, I would choose the line graph, the trend of the line graph keeps getting higher and higher, which means the sales gets better and better.
