A lift ratio greater than 1 indicates a positive association between two items, meaning they are more likely to be bought together than separately. A lift of 1.52 suggests that the likelihood of both items being purchased together is 52% higher than the likelihood of purchasing the breakfast sandwich alone, based on random chance.
