**Bar Graph:**

**Advantage**- It is best for comparing data across categories.

**Disadvantage**- If the interval is too large then you won't be able to see the range between each bar easily.

**Double Bar Graph:**

**Advantage-**It is best for comparing 2 sets of data across categories.

**Disadvantage**- If the interval is too large again then you won't be able to see the range between each two bars easily.

**Line Graph:**

**Advantage-**It is best for showing changes in data overtime.

**Disadvantage**- It can be hard to find out what each number is because it may not be accurate.

**Circle Graph:**

**Advantage**- It is best for comparing categories to the whole using percents. The sum of all the percents in a circle graph is 100%

**Disadvantage**- This graph is only used for graphs dealing with percents.

**Pictograph:**

**Advantage-**It is best for comparing data that can be easily counted and represented using symbols.

**Disadvantage**- It doesn't give the exact number of each category so it is harder to find out.

3 misleading graphs ....

2a) The 2 graphs that would show it accurately would be a line graph and a bar graph.

2b) Yes I would keep selling the pizza subs because each week there are more items being sold.

4: I would choose the line graph because it shows how each month more and more people are deciding to buy the healthier foods rather than the other ones.
