Support
Support measures how frequently the items occur together. Imagine having a shopping cart in which there can be a very large number of combinations of items. Some items that occur rarely could be excluded from the analysis. When an item occurs frequently you will have more confidence in the association among the items, since it will be a more popular item. Often your analysis will be centered around items with high support.
