The AA. share their experience in getting students to develop basic programming skills by providing them with exercises in descriptive statistics, nearest neighbor analysis, median center of a set of points, and networks as matrices. Ideas
The analysis of turbulence time series: statistical and correlation approaches using the MINITAB package
Technical and software bulletin 1993
Correlation ; Geophysics ; Hydrodynamics ; Model ; Runoff ; Sediment transport ; Statistics ; Time series ; Turbulence
The theoretical basis and use of statistical and correlation approaches for the analysis of turbulence time series are described. In particular, the analysis of data from high frequency current meter measurements using MINITAB is presented
The estimation of variogram functions is illustrated by using precipitation and deposition data. The main characteristics of the variogram and kriging are discussed and interpreted. The statistical methodology outlined in this paper is fundamental

The effects on the uptake of immunisation of transport, time-space, and gender-role constraints, among a wider range of influences, are assessed statistically.
Application of a statistical ordination method to species abundance date for use in a university-level biogeography course as a way of teaching the way in which the distribution of plants and their organization into communities are described
. In this article, the main locational factors are suggested as being related to natural resources. This hypothesis is supported statistically (G-test).

Perimeter shape of drainage basins is evaluated as a control of annual runoff depth from small Sierra Nevada basins underlain by granitic rocks. In contrast to three perimeter shape ratios, none of which contributes a statistical explanation

The statistical model of flow-duration curves is applied to all rivers in the study area, a subset of which are chosen and discussed in detail. Results are presented as a series of maps of each of the parameters of the chosen parent distribution

The aim of this paper is to outline a land classification system for reclaimed mined lands based on the use of topoedaphic units. The AA. describe the statistical methods used to delineate topoedaphic units and the discriminant model developed

In the present study a relatively continuous composite faunal sequence is reconstructed from sections at three close localities. The mollusk faunas were analysed statistically in order to propose a reliable climatic reconstruction of the Holocene
