-**Summary:​** In this workshop, you will learn the basics of multivariate analyses ​for your own data. You will learn to choose appropriate distance metrics and transformations ​for clustering, unconstrained ordinations,​ and to perform Principal Component Analysis, Correspondence Analysis, Principal Coordinate Analysis and Nonmetric ​MultiDimensional Scalingto find patterns in your community composition data!+**Summary:​** In this workshop, you will learn the basics of multivariate analyses ​that will allow you to reveal patterns in your community composition ​data. You will first learn to choose appropriate distance metrics and transformations to then perform ​various multivariate analyses: clustering analysis, ​Principal Component Analysis ​(PCA), Correspondence Analysis ​(CA), Principal Coordinate Analysis ​(PCoA) ​and Non-Metric ​MultiDimensional Scaling ​(NMDS).
