Abstract
A method for establishing a modal profile and separating inclusions in mapping units is presented. The statistical concepts and implications are discussed. Horizon thicknesses of 100 soil profiles in a 10-by-10 grid on a stable, remnant, upland terrace were used as the basic data to demonstrate the method. All horizon thicknesses did not follow normal frequency distributions, the Ae and AB were skewed and the depth to carbonates exhibited a tendency to a bi-modal distribution, whereas the Ah and B horizons approached normal distributions.This publication has 7 references indexed in Scilit:
