Chapter 5 p. 35, lines and : should read: in which case there is at least one aggregate spanning the entire volume of the system, p. 374, add to the paragraph ending after Eq. (5.7): Equation (5.7) assumes that the sample size n is sufficiently large that it represents the whole population from which the sample is withdrawn. Otherwise, one needs the sample variance, which is obtained by multiplying the right hand side of Eq. (5.7) by the factor: n/(n - ). p. 375, replace the text from the top with: It is seen that the variance is the second moment of the distribution about the mean, m, while the mean itself is the first moment about the origin. wo higher moments are often used to further characterize distributions. he third moment about the mean, m 3, is a measure of the asymmetry of the distribution, and from it may be computed a dimensionless descriptor termed the skewness, sk: sk = m 3 m 3 / = Σ f i (d i d )3 (σ ) 3 /. (5.9)

4 4 Positive values of the skewness describe distributions that tail to the right, while for negative skewness values, they tail to the left. For the distribution of Fig. 5-0, sk =.30, indicating strong tailing toward the larger particle sizes. For finite samples representing a larger population, a sample skewness is obtained by multiplying sk by the factor: n(n ) /(n ). A further descriptor of the distribution, termed the kurtosis, ku, is constructed from the from the fourth moment of the distribution, m 4, and is defined as: ku = m 4 m = Σ f i (d i d )4 (σ ). (5.0) (n )(n +) he sample kurtosis is obtained by multiplying by. A high kurtosis (Greek (n )(n 3) = "peakedness"), for a symmetrical distribution, means the central peak is high and sharp. For a Gaussian distribution, described below, ku, has a value of 3, while for uniform (flat) distributions it is.8. he first four moments of a distribution (or parameters derived from them) allow a quite detailed reconstruction of any monomodal distribution.
