S4.2 Look at data to find patterns and exceptions.
Candidates should be able to:
find patterns in data that may lead to a conclusion being drawn
look for unusual data values such as a value that does not fit an otherwise good correlation
Notes
A formal treatment of outliers, for example in box plots, will not be tested.
Examples
