Statistics is concerned with the collection, ordering and analysis of data. Data consist of sets of recorded observations or values. Any quantity that can have a number of values is a variable. A variable may be of one of two kinds: (a)Discrete — a variable that can be counted, or for which there is a fixed set of values,(b)Continuous — a variable that can be measured on a continuous scale, the result depending on the precision of the measuring instrument, or the accuracy of the observer.
