Learn about the experimental variogram in this 34-minute lecture from NPTEL-NOC IITM. Explore the key concepts and applications of experimental variograms in geostatistics, including how they are calculated, interpreted, and used to analyze spatial variability in data. Gain insights into the importance of variograms for spatial interpolation techniques like kriging and understand how they help characterize the spatial structure of variables in various fields such as geology, environmental science, and mining engineering.
