s of the distribution of observed values of a variable. Two main aspects of such distributions are (a) where the values are generally located within the range of possible values, and (b) the variation in the values. Measures of the <strong>location</strong> of the values aim to reflect the central value, in some form or another, of a distribution. Measures of <strong>spread</strong> aim to reflect the level of variability around the central value.</p>
