Abstract:
:Methods of measuring the general magnitude or central tendency of sets of data are described, including the mean, median and mode. Similarly, methods of determining the degree of dispersion of the observations about the mean, including range, variance, and standard deviation are presented, together with worked practical examples of their use and importance. The use of algebraic notation in statistics is described.
