Combinatorial data analysis

Combinatorial data analysis is when you look at data from different combinations of things to figure out patterns and trends. For example, you might look at data for the number of people who eat a certain type of food in different countries, or you might compare the prices of different products in different stores. By looking at the data in different combinations, you can figure out things like which country has the most people eating a certain food, or which store has cheaper prices.
