advantage of a bar graph is that it is best to use for comparing data across categories.

Disadvantage - it is used to seperate data.

Double bar graph

advantage- it is used to compare two sets a data

disadvantage-it doesn't show the true value

**Circle Graph**

advantage- its best for showing percents

disadvantage- you have to calculate to show the true value

**Line graph**

advantage- you can tell wheather a set of data is increasing or decreasing over time

disadvantage- can only be used to compare data over time

**Pictograph**

advantage- you can see which piece of data is higher or lower

disadvantage- you have to calculate to get the true value

2. How can graphs be misleading? show 3 ways

You can mislead a pictograph if you make one piece of data larger than the others.

You can mislead a bar graph by breaking the y-axis so the intevals will be more closer together.

You can also mislead a bar graph by making one bar larger.

2. a) A line graph or a bar graph would be best for comparing this set of data.

b)I would continue selling pizza subs because every week the sales are going up.

4. a) I would choose a line graph because it shows the data more accurately.

b)
