1. Statistics may point you to the centre of the mass of data. (centrality)

2. Statistics may suggest to you how diversified the data are. (dispersal/lspread)

3. Statistics may reveal to you how closely or distantly certain features within the mass of data are related. (association)

4. Statistics may indicate to you the degree to which the facts might have occurred by mere chance or whether there is a probability of their having been influenced by some force other than pure happenstance. (association/causation)
