Geometric Data Analysis is a way of understanding data that uses mathematics. Instead of only looking at numbers, it looks at shapes and patterns. Geometric Data Analysis helps us to get a clearer understanding of our data, and make better decisions based on what we find. For example, when we look at a map of the world, we can see where the continents are, and how close the countries are to each other, by looking at the shapes. When we look at a picture of someone's face, we can tell their age and gender by looking at the shape of their eyes, nose and mouth. Geometric Data Analysis helps us to see the hidden patterns and information that's hidden in our data.
