Rose's Graph Post

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


2.Graph that can be misleading

  • Colour

  • Increase the area of the bar


  • 3D
