Information – processed data/ data in context providing meaning and structure.  The data has been converted into a format that provides meaning. (Data + Interpretation = Information)

Knowledge – processed information that can be used to make informed decision.  The way that we understand and use the information that we have.

Encoding data

Data is usually coded when collecting data e.g. Greta Britain becomes GB.  Data is encoded because:

Ø  Coded data takes less effort to enter

Ø  More data can appear on the same screen

Ø  Easier to check that the code is correct

 

Advantages:                                                                                                                               Disadvantages

Takes up less momory                                                                          people may be confused over code

Faster to enter data                                                                                                                   Less accurate

Fewer errors                                                                                                      Possible to run out of codes

                                                                                                                              Rely on personal judgement
