Data richness refers to the depth and variety of information contained within a dataset. It encompasses not only the quantity of data points but also the diversity of data types, such as text, numbers, images, and videos. A rich dataset can provide more insights and a better understanding of the subject being studied, as it captures multiple dimensions of information. In contrast, a dataset with low richness may consist of limited or repetitive data, which can lead to incomplete analyses and less reliable conclusions. High data richness is essential for effective decision-making in fields like business, healthcare, and research, where comprehensive insights are crucial for success.
