This course is an introduction to data analysis and data science by means of mathematics and statistics. We analyze real-world data to find patterns, detect trends and better forecast complex systems in nature. This course provides quantitative methods and deep understanding of applications of data analysis in earth and environmental sciences. It covers analyzing a broad type of data related to geology, earth sciences and environmental engineering. Offered as ENVR 4353 and GEOL 4353; credit will not be given for both. Prerequisite: ENVR 3454, or GEOL 3454, or STATS 1301.
