Double Bar Graphs:
Advantage- you can compare two sets of data across categories
Disadvantage- depending on the data, the interval you choose might not work
Advantage- it uses symbols to show the data
Disadvantage- it sometimes will be difficult to use on some numbers like (15, 7, 13 etc)

2. Three ways showing how graphs can be misleading:
2a. A line graph and bar graph.
2b. Yes, I would continue because both of the graphs show that the sales keep getting higher as the weeks go on.
4. I would have chose the line graph since you can clearly see the sales getting higher right away.
4a. Make the heart represent a smaller number.
Make the interval on the line graph smaller.
