Hi there,

Sparse data has a few different definitions, but one with general consensus is that this type of data is fairly rare and may only have entries in a few fields. For example, the binary data we use (the sales data) doesn’t have a wide variety of responses, but just has a 1 for when the attribute is present in the data set. Dense data would have more varying fields and almost all the cells would be complete. Here are some additional explanations below:

Thank you for learning with us!
