In dealing with statistics as data, statistics has developed appropriate methods of collecting, presenting, summarising, and analysing data, and thus consists of a body of these methods. The major characteristics of statistics as follows: Statistics are the aggregates of facts; Statistics must be collected in a systematic manner for a pre-determined purpose; Statistics must be reasonably accurate; Statistics should be placed in relation to each other.
