Data describes speci c settings. because data come from a speci c setting, the nal step in examining data is a conclusion for that setting. In particular, the rst and last steps emphasize that statistical problems are tied to speci c real-world settings and therefore involve more than doing calculations and making graphs. A numerical summary of a distribution should report at least its centre and its spread or variability. The mean x and the median m describe the centre of a distribution in different ways. The mean is the arithmetic average of the observations, and the median is the midpoint of the values. When you use the median to indicate the centre of the distribution, describe its spread by giving quartiles.
