1. GCSE Statistics
Misleading Diagrams

2. Page 107 has a list that looks like this
Scales that do not start at zero or have parts of them missing out giving a misleading impression of the heights of bars, etc.
Scales that do not increase uniformly distort the shape of anything plotted on them
Lines on graphs that are drawn too thick make it difficult to read information
Axes may not be labelled properly
3-D diagrams can make comparison difficult . Often the thing at the front can appear larger than those at the back
Sections of the diagram separated from other parts make comparison difficult (pulled out slices on pie charts)
Using colour so some parts stand out more than others. Generally dark colours stand out more than light colours and make these sections look bigger
Using different width on bars or different sized pictures.
Some data may be excluded
