Graphing Post

1. a)Bar graph

• Advantage: it can easily compare two or three data.
  

• Disadvantage: if the interval is to high, you can't see the range easily between two categories.

b) Circle graph

• Advantage: shows percent if total for each category.

• Disadvantage: if the categories are not in percent, you need to change them into percent which requires work.

c) Line Graph

• Advantage: shows range and outliers easily
  

• Disadvantage: if the interval is too high you can't see the range between the two data
  

d)Double Bar graph

• Advantage: it compares two data across categories

• Disadvantage: if the interval is too high you can't see the range between the two data
