Descriptive Statistics
Shows users how to perform descriptive statistics on a complex dataset labeled "richness_abundance_farm" (N=90). This is a synthetic dataset, where invertebrate species richness and abundance values were obtained from two separate farms.

Creating correlation matrix on genetic dataset
This workflow guides you through creating a correlation matrix using real-world data. We will analyze 11 genes linked to breast cancer tumor development to observe expression rate variations between normal breast tissue and breast cancer tissue. The dataset comprises 572 entries, including gene names, sample information, and FPKM values (Fragments per kilobase per million mapped fragments).
