For example, the measures of central tendency can give the average of a given data set, however it cannot describe how the distribution of data set was done. The network graph G had a diameter, researcher by summaries the basic statistics into graph for better investigation. Sample Space - the set of all possible outcomes of a random phenomenon Event - any set of outcomes of interest Probability of an event - the relative frequency of this set of outcomes over an infinite number of trials Pr(A) is the probability of event A An Introduction to Basic Statistics and Probability – p. 4/40.
