|Geotechnical engineering, engineering geology, geographical information system, and field disaster data collection all require the understanding of the spatial distribution of the collected data. Take the geology as an example, the spatial distribution of geological structures usually determines the feasibility of an engineering project. Therefore, it is extremely important to understand the statistical meaning of the measurement results. Also, in the field of geotechnical engineering, engineers tended to apply very conservative safety factors due to the uncertain nature of the geological materials. As a result, the selection of the proper design numbers was not objective or accurate. To address this problem, it is the goal of this course to introduce the concept of probability so that students could become familiar with statistical concepts such as normal distribution, time sequence analysis, regression analysis, and their applications in the measurements of geological data.
