Abstract : This report presents a method of statistical analysis for particle-size data obtained with the Battelle CI-S-8 impactor. The equations developed in this report give a simplified method for determining the least-squares fit for data represented by a log-normal distribution function. Mathematical equations include: (1) computation of the slope and intercept, (2) transformation substitutions, (3) general results, and (4) application to the Battelle impactor. A sample calculation is given in the appendix. (Author)
