                      «   Data processing is the act of converting raw data into meaningful and useful information.
                      «   Data are the facts, numbers or observations collected to gain new understanding.
                      «   Sorting data means arranging information in a clear and organised order.
                      «   After the data is organised, patterns, trends and unusual results can be identified.

                      «   A trend is the general direction in which data moves over a period of time.
                      «   An anomaly is a result in the data that is unusual or does not match the normal pattern.

                      «   Using data ensures that decisions are based on facts and clear evidence rather than guesses.
