BOB for October 6, 2009

BOB for Graphing

3 things I learned about graphing are:

1) The different types of graphs and what they are best for:

Bar Graph

-bar graphs are best for comparing data across categories

Double Bar Graph
- double bar graphs are best for comparing two sets of data across categories

Circle Graph
- circle graphs are b
est for comparing categories to the whole using percents
- th
e sum of the percents in a circle graph is 100%

Line Graph
- line graphs are best for showing changes in data over time


- p
ictographs are best for comparing data that can be easily counted and represented using symbols

2) The correct terms:

3) To distort a graph

- use an axis break

- change the sizes

- make one stick out using colour

Something I need to improve on, that I didn't do on the assessment is that I need to explain the trend and make a prediction with the conclusion from the graph.
