I would like to share the presentation material about Experimental Variogram that I delivered in the Geostatistics class in the S1 Mining Engineering study program ITB. This material begins with a brief overview of Regionalized Variables and Autocorrelation, before focusing on the concept and calculation of Experimental Variograms. In this session, students also had the opportunity to perform variogram calculations manually as an exercise in class. In closing, I gave homework so that they could repeat and deepen their understanding of the material they had learned. Hopefully this material will be useful, not only for those who are involved in the mining world, but also in various other fields that apply geostatistics.
