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 best for comparing categories to the whole using percents
- the sum of the percents in a circle graph is 100%


















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


















Pictograph
- pictographs 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.
