	In the transaction table excerpt below, a list of transactions is displayed for a single student working on two tutor problems. In ~~this data~~, ~~multiple~~ transactions ~~often exist~~ for ~~a single~~ step (~~the~~ step SCRAP-METAL-AREA Q1~~, for example, is listed in multiple~~ transactions). These multiple transactions are also known as attempts for a given step.		Students may make incorrect entries or ask for hints before getting a step correct. Each hint, incorrect action, or correct action is a transaction; and a step can involve one or more transactions.

			In the transaction table excerpt below, a list of transactions is displayed for a single student working on two tutor problems. Transaction 9 shows that the student correctly entered a '4' in the tutor interface. Transaction 10 shows the correct entry of the '8'. In both cases, there is one transaction for each step. In transactions 11 and 12, we see incorrect entries ('32','4') for the 'Area of the scrap metal'. The student returns to this step in transaction 15 and correctly enters 13.76, but first finds the areas of the square and circle (transactions 13 and 14). The step (SCRAP-METAL-AREA Q1) therefore involved three transactions. These multiple transactions are also known as attempts for the given step.
